What Is GPS: Your Summary

Find the less expensive car insurance here. The Global Positioning System, usually called Global Positioning System, the US military refers to it as NAVSTAR Global Positioning System – Navigation Signal Timing and Ranging Global Positioning System. Actually NAVSTAR Global Positioning System is the official name of Global Positioning System. It is the only operational satellite navigation system.

The Global Positioning System can be used for determining someone else’s definite location that provides a highly accurate time reference almost anywhere on Earth. The accuracy of the Global Positioning System signal itself is about 5 meters (16 ft) as of 2005 and has steadily improved over the last 15 years. Using differential Global Positioning System and other error-correcting techniques, the accuracy can be improved to about 1 cm (.4 in) over short distances.

This system was made by and is controlled by the United States Department of Defense and can be used by anyone, with no charge.

The Global Positioning System is a satellite-based navigation system made up of a 24-satellite network placed into orbit by the U.S. Department of Defense. The system was first intended for military application. It was in the 1980s, when the government made the system accessible for civilian use.

Global Positioning System works in any weather conditions, anywhere in the world, 24 hours a day. There are no subscription fees or setup charges to use Global Positioning System.

The Global Positioning System system is divided into three segments: the space, control and the user. The space segment includes the Global Positioning System satellite constellation. While the control segment comprises the ground stations around the world that are in charge for monitoring the flight paths of the Global Positioning System satellites. And the user segment consists of Global Positioning System receivers used for both military and civilian applications.

A Global Positioning System receiver decodes time signal transmissions from multiple satellites and calculates its position by trilateration.

The expense of maintaining this system is an estimated amount of US$400 million per year, including the replacement of aging satellites. The first Global Positioning System satellite was launched in February 1978, and the most recent launch was in September 2005. The oldest Global Positioning System satellite still in operation was launched in February 1989.

Below is a list some other interesting facts about the Global Positioning System satellites. The first Global Positioning System satellite was launched in 1978.

- A full constellation of 24 satellites was achieved in 1994.
- Each satellite is built to last about 10 years. Replacements are constantly being built and launched into orbit.
- A Global Positioning System satellite weighs approximately 2,000 pounds and is about 17 feet across with the solar panels extended.
- Transmitter power is only 50 watts or less.

Wondering how it works?

Global Positioning System satellites circle the earth twice a day in a very accurate orbit and broadcast signal information to earth. Global Positioning System receivers take this information and use triangulation to calculate the user’s exact location. Basically, the Global Positioning System receiver compares the time a signal was transmitted by a satellite with the time it was received. The time difference tells the Global Positioning System receiver how far away the satellite is. Now, with distance measurements from a few more satellites, the receiver can determine the user’s position and display it on the unit’s electronic map.

A Global Positioning System receiver must be locked on to the signal of at least three satellites to calculate a 2D position, the latitude and the longitude and then track movement. With four or more satellites in view, the receiver can determine the user’s 3D position (latitude, longitude and altitude). Once the user’s position has been determined, the Global Positioning System unit can calculate other information, such as speed, bearing, track, trip distance, distance to destination, sunrise and sunset time and more.

Important Things To Know About Solar Power Energy

What Is Solar Power Energy?

There are many important things that you should know and understand regarding the matter of solar power energy. In the simplest terms, the term solar power energy is used to describe a number of methods which are harnessing energy from the sun. Solar technologies use the sun’s energy and light to provide such elements as heat, light, hot water, electricity, and even cooling for homes, businesses, and industries.

In other words, the sun has produced energy for billions of years, and solar power energy is the radiation which then reaches the earth. This solar power energy can then be converted either directly or indirectly into other particular forms of energy, such as heat and electricity, for instance. Solar energy can be used for heating water for domestic use, for the space heating of buildings, the drying of agricultural products, and even for generating electrical energy.

Solar energy has been around and been used since the prehistoric times, and before 1970, some research and development had been carried out in a few countries, with hopes to exploit solar energy more efficiently, however most of this work remained academic for the most part.

Solar energy is, in fact, even being used in India for heating the water for both industrial and domestic purposes.

Solar energy is considered to be the most readily available source of energy, and it is easily the most important of the non-conventional sources of energy because it is non-polluting and therefore helps in lessening the greenhouse effect. The electricity that can be stored from solar energy can be used for many purposes, such as: domestic lighting, street lighting, village electrification, water pumping, desalination of salty water, powering of remote telecommunications repeater stations, and railway signals – to name a few.

The only real problem with solar energy is that it only works when the sun is shining, so on cloudy or dark days or during nights the power plants cannot create energy. There are other certain hazards that are possible with solar power; proponents of solar energy present facts, figures, and graphs support claims that energy from the sun would be less expensive, considering that conventional fuel supplies dwindle and technology of solar energy systems improves.

Even so, one must stop to consider what will actually stop the solar energy equipment manufacturers and solar power companies from raising prices when they achieve a monopoly and other fuel sources disappear.

Understanding Live Data Backups With SBAdmin

As the need for system availability increases, especially in 24 hour operations, the backup “window” must decrease to prevent data from changing while being backed up. Go to data storage for more information.

Backing up “live” data can cause erroneous or partially updated files after such data is restored from a backup. This is particularly problematic with databases, which typically have relational data that must be kept in sync.

SBAdmin includes the ability to perform a snap shot, or point in time backup of any live data contained in Logical Volumes. Logical Volumes are software storage devices used exclusively on AIX systems and are quickly becoming a standard installation storage configuration on Linux systems.

Logical volumes are created by the Logical Volume Manager (LVM) package. SBAdmin performs snap shot backups by backing up an offline copy of all data in the logical volumes.

This allows users to continue to access and modify data in the online copy, while the backup includes all data as it was when the backup process started. This ensures the relational data, when restored, is all at the same point in time, no matter how long the backup takes.

SBAdmin uses a Split Mirror Backup process on AIX systems to capture data from an offline copy of a mirrored logical volume. All AIX systems use the Logical Volume Manager (LVM) for storing all data.

Logical volumes may be mirrored, keeping a separate up to date copy of all data as the data is changed. SBAdmin will allow you to configure split mirror backups, which will break off a copy of the live data, and use the offline copy to perform the backup. Refer to data storage for more information.

This is especially useful for backing up live data such as Oracle, DB2, or MySQL databases. When the backup is complete, SBAdmin returns the mirror and syncs it up with the online copy. LVM also allows for 2 mirrors (3 copies) of a logical, so SBAdmin can break off one copy while data and system availability is still preserved using the remaining mirrored copies.

A backup job configured to use split mirrors, whether a specific file system, raw database, or the entire system, performs all the steps in splitting off copies, backing up, and re-syncing the copies making the process automatic and transparent to the user.

On Linux systems SBAdmin uses the Snapshot Logical Volumes. Most Linux systems now support the Logical Volume Manager (LVM) for storing all types of data, from file systems to raw database data. SBAdmin provides a simple user interface for performing LVM snapshot backups.

Now, when performing any SBAdmin backup of LVM data, a copy of the live changing data is automatically created, allowing the original data to be “frozen in time” at the point of the backup. At the same time, users can continue accessing and updating the changed data while the backup is running.

When this “hot backup” completes, the system is returned to normal operation, and the entire process is completely transparent to the users. The interface gives you several options such as which logical volume to create the snapshot, whether to create them all at once or sequentially and whether to continue or fail if there is a problem.

Since the snapshot backups are performed on any data residing in logical volumes, including raw databases and file system data, any and all data, even on a full system backup, may be captured. Visit data storage for further information.

E-Book Readers Are Greener

In 2008 the American book and magazine industry sector was responsible for the felling of 125 million trees. A lot of publishers are environmentally aware and use sustainably sourced wood pulp for their paper. Simply put, they plant a tree for every one they cut down. However, not all do this and even those who do often fail to take account of the huge quantities of water and thermal energy used in the paper production process.

The carbon footprint of the typical book is 7.5 kg of CO2 over the course of its lifetime. However, if you get in your car, drive to the bookstore to pick up your book, and then drive home again, the carbon footprint of your book is doubled. It’s surprising how relatively small actions like this make such a difference.

So it should be no surprise to discover that electronic book readers – such as the Amazon Kindle – are kinder to the environment. Besides the fact that no paper, ink or water are used in the manufacture of electronic books, the delivery method – download from the internet by either standard connection or 3G wireless technology – is significantly more environmentally friendly.

However, it would be incorrect to imply that e-book readers have no environmental impact. Clearly they use both materials and energy in the course of the manufacturing process of the reader device. They also require electrical power to operate. However, even taking these factors into account, they are still much better for the environment than the continued use of traditional printed books, magazines and newspapers.

It is anticipated that in 2009, e-book readers will be “carbon neutral” – the CO2 saved by the use of electronic media will almost exactly balance the CO2 used to make and power the devices. Thereafter, as usage grows, the manufacture and operating “cost” will be more than compensated for by the savings [spin|gained|obtained[/spin] by avoiding the production and distribution of traditional paper based books and magazines.

The majority of people will choose their Kindle reader based on the fact that it’s handy, trendy and that it offers a way for them to save money on books. The fact that it’s better for the environment may be no more than a secondary consideration for many – even so, it will have a huge positive impact in the future.

Hidden Spy Cameras & Spy Cams are Exclusive and Affordable

Previously it s said that we have to appoint an investigator in order to get rid of the problems which we may have to face in life due to some invisible events taking place. But today all of us have become an investigator and analyze all the events taking place in and around our homes and our work places with confidence and evidence. This can happen with the help of the hidden cameras or the spy cameras which are in built with the innovative features incorporated in the big CCTV cameras up to the mini cameras. Some of the mini spy cameras are intended in the form of button, wrist watch, neck tie, and sun glasses. This is intended completely and amazingly . Its features are matchless and these can be worn on any part of the body easily depending upon the product. Using this product we can analyze and investigate the problems which unnecessarily creates a mess at our home or our work place. The complete information about all the mini spy cameras and many other cameras like the hidden camera, nanny camera, and many more can be obtained from all the leading websites of the spy cameras, through the internet facility that is available at an ease these days.

I have a habit of wearing sun glasses and so when I surfed through the internet for the information about the latest cameras, I immediately made up my mind that I would go in for the eye glass case camera. Its appearance looked like a usual glass case which also has a safe clip so that the pocket could hold the glass case easily . After reading all the features of this camera I even felt that this is the leading and an astonishing mini camera which is very useful. There are many cameras which emerge in this form which also have color and also black and white versions and both are evenly brilliant and inexpensive too.

If one wants to have a video recording up to 2 hours nonstop then he/she has to attach it with a 9V battery and if one’s need is more than that then he/ she can even use 8 AA batteries which can further assist in the recording procedures continuously up to 7 hours. The clip which is fixed to the Eye glass case camera for safe keeping or hold to the pocket is very appropriate and thus it can be carried by one and all quite effortlessly. A CCD pinhole camera which is of 1/3” is attached in the camera which has the potential to give immediate images up to the whole area of estimated 78 degrees. It has the capacity to capture clean and clear images.

The ultimate consequence is that if we use such type of equipments for inspection then we can even defend ourselves and our property either we are in office or at home. In the office if we wear these types of mini body worn cameras, no one will locate or guess that we have worn this to keep an eye on them.

Methods to Initiate an Internet Business

In today’s thriftiness many of us find themselves all of a sudden out of work or in need of further funds. In a number of cases the cost of child care has gotten so last that people just can’t open to work right of the home. No matter what the reason, you may be thinking about how to start a little home run business.

We won’t bore you with the statistics near how new companies are cyclical because you possibly already love them. One of those reasons lies in the absence of first planning that is needed whether you have an online enterprize or a land-based business. Here are 2 steps that you’re going to need to take to ensure that your business gets off to a serious start.

The biggest mistake near start-up businesses make is to burn off more than than they can chew. When someone comes to a decision to start a home business they have a tendency to think of their products and services as an element of a team effort. This is particularly true if the person is coming out of a large office environment. It is important to start little with services that you love you can offer yourself with no help.

To work out the time vs project ratio you’ll need to figure out how long it has you to complete a project from start to finish and add in the time itwill take to have the product to your customer. If you do this exercise with pencil and paper itwill be far easier for you to work out what kind of time will be needed to finish a fixed number| specific number| specific amount} of projects. Without extra this exercise the general public will forecast that they can clear many more projects than they have hr in the day to do because they do not have a lot of have doing rank projects, start to finish, on their own.

eBay: The First 10 Years. Helpful Things to Remember

If you’ve ever read an article about eBay, you will have seen the kinds of incomes people make – it isn’t unusual to hear of people making thousands of dollars per month on eBay.

Next time you’re on eBay, take a look at how many PowerSellers there are: you’ll find quite a few. Now consider that every single one of one of them must be making at least $1,000 per month, as that’s eBay’s requirement for becoming a PowerSeller. Silver PowerSellers make at least $3,000 each month, while Gold PowerSellers make more than $10,000, and the Platinum level is $25,000. The top ranking is Titanium PowerSeller, and to qualify you must make at least $150,000 in sales every month!

The fact that these people exist gives you come idea of the income possibilities here. Most of them never set out to even set up a business on eBay – they simply started selling a few things, and then kept going. There are plenty of people whose full-time job is selling things on eBay, and some of them have been doing it for years now. Can you imagine that? Once they’ve bought the stock, everything else is pretty much pure profit for these people – they don’t need to pay for any business premises, staff, or anything else. There are multi-million pound businesses making less in actual profit than eBay PowerSellers do.

Even if you don’t want to quit your job and really go for it, you can still use eBay to make a significant second income. You can pack up orders during the week and take them down to the post office for delivery each Saturday. There are few other things you could be doing with your spare time that have anywhere near that kind of earning potential.

What’s more, eBay doesn’t care who you are, where you live, or what you look like: some PowerSellers are very old, or very young. Some live out in the middle of nowhere where selling on eBay is one of the few alternatives to farming or being very poor. eBay tears down the barriers to earning that the real world constantly puts up. There’s no job interview and no commuting involved – if you can post things, you can do it.

Put it this way: if you know where to get something reasonably cheaply that you could sell, then you can sell it on eBay – and since you can always get discounts for bulk at wholesale, that’s not exactly difficult. Buy a job lot of something in-demand cheaply, sell it on eBay, and you’re making money already, with no set-up costs.

If you want to dip your toe in the water before you commit to actually buying anything, then you can just sell things that you’ve got lying around in the house. Search through that cupboard of stuff you never use, and you’ll probably find you’ve got a few hundred dollars’ worth of stuff lying around in there! This is the power of eBay: there is always someone who wants what you’re selling, whatever it might be, and since they’ve come looking for you, you don’t even need to do anything to get them to buy it.

All The Basics About Website Marketing

Blog marketing is one of the latest trends of marketing online that you are going to find. Blogs which are also known as web logs are very popular in this day and age. You can make a blog on any particular subject that you want and then publish it for the world to read.

If you are just beginning in internet marketing, you are going to find that starting a blog is very easy to do. Anyone can sign up for a free blog, and then proceed to market basically anything that they want to. Because blogs are free to have and make, this makes blog marketing even better. Where as if you have a website, and are wanting to market things that way, you would have to pay for your domain, pay for your hosting of the domain, and then know some HTML or hire a website designer.

Search engines love blogs, and are always pretty fast to index them. Getting yours out there for the world to see is not going to be hard. There is this cool tool that you can use every time you update your blog that is known as pinging. Pinging your blog after every entry that you make will let everyone know that your blog has a new entry and updated.

Depending on your overall goal with blog marketing, you can update your blog as frequently as you like. Which could be daily or weekly. Whichever you choose, just be consistent with it. If you start out updating daily, stick with it. This way your blog readers will know that they can check your blog daily for new postings.

If you are wondering exactly what you can market in a blog, you can market whatever you want to. However, it is best to stay within one market in your blog. If you have several different things that you would like to promote, and none of them really fit together well, you can create a blog for each market. Remember that if the markets are not related, do not mix them on your blog. For example, if you have a blog on vacuum cleaners, you will not want to also mix in television sets on the same blog. This is because both vacuum cleaners and televisions sets are two different markets. But, you could mix vacuum cleaners and handheld mini dust busters. Make sense?

There so many things that you can market in your blog. Whether you want to sell your own products and services or someone else’s and make a commission off of what you sell. The sky is the limit when it comes to marketing. Affiliate links work great in blogs as well. Signing up to sell other people’s products and then marketing them in your blog is a great idea.

If you are considering having both a blog and a website that will work if you have enough information to cover in both. Linking them both together is a great idea if you do decide to have both. You can always use the website to hold your main information and products, and the blog to promote them and discuss any issues regularly.

Wondering about hosting? If you have a website, you can either host your blog on the same server you use for your site, or you can leave it where it is. The choice is ultimately up to you, either way you can have successful blogs that will begin to bring in revenue to you.

Getting links to your blog is a good way to gain new readers. Another great tool you can use is the RSS feeds. When you use the RSS feeds, it allows people to publish your blog on their site, and in return it gets you more visitors.

Blog marketing can be pretty effective if it is done right. However, you cant just set up a blog and expect people to find it. Get your blog out there and make it known to others just as you would a website. Exchanging links with others will help, so will article marketing using your blog.

Blog marketing is easy and anyone that wants to can do it. Getting your blog out there and known will be your biggest challenge, but just know that the harder you work at it, it will pay off. Find sites that are related to the market you are promoting, but not in direct competition and ask for link exchanges.

Kindle Ebook Reader Family – Will It Be Amazon’s iPod?

The Amazon Kindle seems to be the current hot “must have” gizmo on the market at the moment. It seems very much as if the ebook reader is an idea whose moment has arrived – and the kindle ebook reader is certainly the best example of such a device on the market right now. It is also, and let’s be frank about it here, cool.

The Kindle has frequently been compared to the Apple iPod – which, incidentally, now has a kindle application that allows you to read kindle books on it – by a number of industry insiders. Indeed, going right back to the launch of the original Kindle in November of 2007, Steven Levy’s Newsweek cover article stated that the Kindle was the “… iPod of reading”. Two and a half years later it seems that drawing parallels between the two devices might go some way towards understanding the current phenomenal success of the Kindle – and perhaps even allow some insight into what could occur in the near future.

Amazon supremo Jeff Bezos is quoted as saying, again way back in 2007, that “This [the Kindle] isn’t a device, it’s a service.” – and that is absolutely critical to understanding why the Kindle dovetails in so well in Amazon’s business model.

Some criticisms have been levied at the Kindle’s high price – it currently retails at $359 for the Kindle 2, slightly reduced from the original Kindle price of $399. The original iPod was priced at $399 when it was launched – prices have reduced as the product was first accepted, and then crossed through mainstream to practically ubiquitous. At the same time functionality has increased.

Apple is, and has been for some time now, synonymous with music downloads and has increased the available portfolio of products to include videos, games and a host of applications for the iPod. In a similar manner, Amazon is strongly associated with books, making the kindle a perfect choice of product for them. The recent pre-launch of the larger Kindle DX is noteworthy, not solely because of the numerous technical enhancements that it offers, but because it improves Amazon’s capability to deliver newspapers, magazines and even educational textbooks to its customers.

It would be wrong to downplay the technical aspects of the Kindle series of readers completely of course, but it seems that, for Amazon, the technology is a means to an end rather than the end itself. In fact, as far as e-book reader technology goes, Amazon are somewhat late to the party when you bear in mind that there have been previous contenders – such as the Franklin ebook (no longer in development but still available from some sources) available since 1999, and Sony have had ebook readers for quite a time. There are a number of others, some have already vanished, others are soldiering on without, currently at least, attracting anything near the volume of interest generated by the Kindle.

Another key advantage enjoyed by Amazon at this time is the 3G wireless technology utilised to allow Kindle users to download their ebooks in under 60 seconds without the need for a computer or an internet connection – and without being tied in to a monthly contract or having to furnish a download fee. It’s a perfect example of the way Amazon have [leveraged the technology to provide a perceived benefit for their customers.

No monthly connection fee plus no download charges means that customers do not feel tied in or committed to the Amazon service, a significant factor bearing in mind the relatively high cost and the current economic climate. Of course, whilst customers will be able to buy ebooks elsewhere to read on their Kindle, it is still going to be considerably easier for them to purchase from Amazon’s huge, and ever expanding, selection of Kindle friendly books. Amazon are going tolot of repeat business – in the same way as Apple do with their iTunes store.

Using the iPod history to predict the Kindle’s potential future, it seems improbable that the Kindle will have it all its own way. As previously stated, there are , even now, a number of existing alternative ebook readers available – the Sony PRS is most likely the most significant player aside from the Kindle at the moment, but there are others. These will either develop and provide strong competition for the Kindle or disappear from the marketplace.

Also worth considering is the fact that there are a number of new readers in development. Plastic Logic, has a Kindle DX sized reader in the pipeline which has been scheduled for release in 2010. Rumours abound relating to the release of an Apple tablet based notebook, suggested to be aimed at the gap between an iPod Touch and a full blown MacBook. It wouldn’t be too fanciful to imagine that Apple might grow their iStore to include ebooks just as they expanded it to include videos after the release of the iPhone and iPod Touch.

And it’s not just wider competition based on improved reader technology that Amazon might have to face. In March of 2009 Google and Sony announced that Google’s huge library of public domain e-books would be made available gratis on Sony’s reader. That’s a total of 600,000 titles and is a definite signal that the ebook reader marketplace going to be strongly contested in future.

At the moment Amazon is sitting pretty. It has a vast and, most important of all – the Amazon Kindle is cool. Whether or not it grows into a ubiquitous iPod type product or not in the face of what will surely be fierce competition only time will tell. Amazon have been more than smart so far, so it seems likely that they will be a major player in this emerging market for a long time to come.

One thing seems guaranteed, we will all have the option to read books, magazines, newspapers and even college textbooks using portable digital readers in the immediate future. As competition, volumes of scale and advancements in technology combine to drive prices lower this will become an increasingly popular choice for many, possibly even the majority of, readers. The way we read is set to change, possibly more quickly than you might imagine.

Expanding your Knowledge of 3D Animation

The 3D animation is the current day cutting edge graphical presentation that is made possible through computer software and digital generators. This current day graphical tool is now the standard in motion pictures, video presentation formats, animated films, commercial advertisements, virtual walk through and web presentations and stuffs. We are at present seeing 3D graphics animation in many forms which include 3D presentations, audio visual illustrations, 3D scientific and medical graphics and many other everyday applications.

In order to appreciate the underlying principle behind 3D graphics and animation, it is key that we clearly understand its basic distinction from the customary 2D animation. The 3D graphic application has the representation of geometric variables which are contained in the computer in executing the calculations that will produce the 2D generated graphics.

The rendered graphics in 2D design are utilized for the virtual and real time figures in 3D graphic illustrations. The 3D graphic illustrations present images at many angles including an aerial shoot to produce a near perfect illustration that is virtually real in every aspect. This feature is known as motion tracking, which presents the virtual representation of the actual camera motion tracking representing the real camera motion shoot.

The 3D graphics originate from a basic idea or concept. The concept then progresses with the needed details and elements of a design and flow of the graphics in the form of storyboards. The topic and character development are components of the initial work done by animators based on an predetermined design and plan. The preparation of the storyboard permits the generation of important frames to conclude the flow of motion as shown in the storyboard.

The components or characters in 3D graphic are known as 3D models. These are essentially data files that contain the data that are required to produce 3D images. On the other, the process of key-framing in 3D graphics includes the assigning of correct values to the variables at the precise points in the motion flow of graphics in a succession of frames to make the desired animated sequence.

You will necessitate a texture map in order to maneuver the pattern or structure of the 3D guides . This is the application that lets the graphic designer to control and modify the diffuse surface color at the most fundamental pixel level. This is attained in texture mapping by creating bitmap images of 3D models within an existing 3D scene.

What are the basic abilities needed in 3D graphics and animation work? In the chance you may be involved in a 3D graphics and animation project, it is mandatory that you have the power to think about details and have the ingenuity in creating design schemes and characters.

A occupation in 3D graphics and animation is both exciting and hard . It offers a lot of career breaks and your advancement in this field is based on your performance as a member of a larger team. Because of its broad application for a large range of concerns and interest, 3D graphics and animation is predicted to be one of the most demanding and rewarding jobs for a wide range of individuals and professionals.
