The space segment is probably one of the most expensive and highly advanced of the three. This segment consists of a net of twenty four satellites that make a routine orbit around the whole planet. Each satellite is specifically located eleven thousand nautical miles in the earth's outer layer, and have their own orbits to follow. Orbits take 12 earth hours, and each satellite is equipped with an atomic clock that synchronizes both data transmission and space allowance between each satellite to prevent bumping towards each other and to also prevent service localization.

The control segment entails various ground stations located in different parts of the world. These are observation towers or radio towers that continuously transmit data from various satellites that pass by the area. Some of these locations are located in Hawaii, at the Kwajalein. Diego Garcia in the Indian Ocean, the Ascension Island located in the Atlantic, Cape Canaveral in Florida, and one more in Colorado. There are other large ground antenna stations that send data for monitoring purposes to keep the satellites in working order. The master station for all the ground segments is located in Colorado, in the Schriever Air Force Base.

The user segment are those that are being held by the people that use this system. They are called GPS receivers, as they receive data that is sent by the satellites and processed by the ground stations. There are at least a hundred of these models scattered around the world, from something as small as a wristwatch to those in a car. The smallest could weigh as little as an ounce.

The request sent in by the user is handled by the space segment. The space segment sends back data according to location by which the user would receive the fastest response time. Monitoring stations make sure that the satellites send integral data back to the receiver. All collected data is sent to the master control station for processing and storage. The ground antenna from the master control stations sends back critical data to the satellites to adjust in cases where it is needed.

Plotting out directions is, well it was such a time waster. Especially on long trips. My wife had to sit in the front seat and copilot our trips to make sure we were on the right path. Now with GPS all she has to worry about is packing everything she can into her overly large suit case. To bad my smart phone can't lug that thing into the trunk for me.

Working at break-neck speed, Wernher von Braun, the new head of NASA, immediately began to explore the possibility of sending human beings into space. Within the first year of their inception, NASA had launched the Explorer 1 satellite into space. Dubbed Project Mercury, this program involved seven original astronauts, of whom, Alan Shepard became the first American into space, while John Glenn would become the first American to orbit the earth.

Revolutionary GPS tracking devices were used to track their location, altitude, and rates of speed. So coveted was this GPS technology that it remained classified until 1983, when a Soviet interceptor aircraft shot down a civilian Korean Air airliner, killing everyone on board. The plane had strayed into Soviet airspace and although the Soviets had probable cause, had the airliner had accurate navigational systems, the tragedy could have been avoided. President Ronald Reagan subsequently declassified GPS tracking systems for civilian use.

The first successful GPS tracking system, created by the Navy mind you, was code-named Transit. It used five satellites to triangulate positions around the globe. With the Space Race underway, NASA began implementing a new tracking system, called the Global Positioning System (GPS). The system involved the use of satellites to track the position and location of both spacecraft and intercontinental ballistic missiles.

Global positioning systems have not only become ubiquitous, they've become the preeminent navigational systems used by scientists and taxi drivers alike. In fact, law enforcement uses GPS tracking to find stolen cars and keep tabs on criminals on bail or probation. Now, not only can someone find where they are on a city grid, but also he or she can find nearby businesses and restaurants.

Your GPS tracking device is closer at hand than you thought. Actually, it's ringing now.

Chevrolet states in its latest advertising campaigns that it is "A Legacy Built On Dependability." This is so true when you consider the Chevy truck. The 2008 model year demonstrated Chevrolet's dedication to creating the best trucks in the industry by introducing three uniquely outstanding truck models to the world. No question about it. Avalanche, Silverado, and Colorado are the best trucks in their own class. Check out Chevy auto parts online to see what is available.

Silverado's rock-solid chassis makes it a favorite choice of country tough guys. When you have to travel the bumpiest dirt roads in America with a large load in the bed, you want something that can get the job done. It has been said that Chevy owners are so confident of the durability of their trucks, that their Chevy truck would be a perfect inheritance for future generations to come. Having engine sizes and chassis capacities to haul any load, these trucks have the towing capacity to get the job done. With the technology under the hood to make it the industry leader, the Silverado's powerful 6.6L V8 Turbo diesel can definitely haul the biggest loads in rough terrain or miles down the longest interstate highway. Cargo handling in extended cab models is made easy with rear cab doors having 170-degree access.

For guys who love sporty vehicles, you can't beat the versatility of the Chevy Avalanche. What sportier truck enthusiasts love about it is that it is so flexible. Most obvious is the innovative system to make the truck bed longer. What happens is that the rear seats fold down, rear glass removes, and the midgate system drops down. Essentially it turns it from a crew cab short bed to a two door long bed pickup. As you let down the midgate, the removable wall that separates the cabin from the bed, you will find that there is plenty of room for storage. You could even sleep there if you needed. Talk about a truck bed! For this reason, you will discover that the Avalanche is really an outdoor adventure vehicle ready to take you to mother nature's doorstep. It is very easy to slide two sleeping bags into the truck bed, so it eliminates the need to pitch a tent.

The new breed of Chevy truck can save the consumer money while also providing outstanding performance. The Chevy Colorado is now using a smaller 3.5L engine and still packing a nice punch. As a model co-developed with the Japanese manufacturer Isuzu, this pick-up truck has all the much sought after features such as durability, flexibility, comfort and power all rolled into one.

Trucks usually haul cargo in long trips so Chevrolet also made entertainment and information connectivity a top priority for new truck owners. Equipped with CD/MP3 entertainment and state-of-the-art Radio Data System compatible radio systems, Chevy outdoes itself. Avalanches now have a navigation radio built in.

Most of Chevy models now use General Motor's patented Active Fuel Management technology. Switching from 8 cylinder to a fuel-saving four cylinder mode, this technology helps increase the overall fuel savings of the truck by lessing the gasoline used while not under a heavy load. The truck's on-board computer does everything automatically as you drive to switch between the modes.

An environmental statement made by Chevy's new truck line, is their new ability to burn cleaner E85 ethanol-blended fuel. Ethanol mix E85 is a cleaner burning fuel that releases less green house gases into the environment. Climate change is becoming an issue that the auto industry can no longer ignore and Chevrolet is truly creating an "American Revolution" in terms of changing the status quo in Detroit.

Chevy trucks these days are tough and environmentally friendly. It doesn't have to be one or the other. If you don't have a reliable truck, check out what Chevy is doing nowadays. You will be amazed at what they are offering in a new truck. If you buy one, you won't ever regret it!

Lawyers are not cheap, and they certainly aren't always easy to work with. If you don't already have a good attorney to work with, odds are you will be in for a ride as you try to find one you can trust. Through judging them on several aspects, you can make the chase much shorter.

Sketchy criminal defense lawyers will try to push you into parting with your money early on. They may even try to tell you that your options in criminal defense attorneys are limited because other lawyers aren't competent. Be wary when a lawyer mentions this, because it is a common tactic to make themselves look better. And while it may work on some, it just shows how low an attorney will sink to others.

Always look for a history behind an attorney. Ask them to give you instances in which they did great, and even when they didn't do so well. Inexperienced attorneys will shy away from such conversations because they think it hurts their credibility. If they can't show you such information, you are better off siding with an attorney that can be honest about their services.

Watch out for the "secret connection" tactic that some criminal defense lawyers will pull. They may state that they are extremely good friends with the judge or prosecuting party in order to make you think they have an influence over the court case. Not only would that be illegal to pull strings in such a manner, but in reality the this is just a trick to gain trust and build upon any stored hope you have.

The deal-breaker for many is when you ask an attorney for his or her personal phone number. Ask an attorney if you can call them at any point, day or night. If he or she hesitates, the attorney probably doesn't care about clients as much as others would. A good attorney should focus on customer service and not be selfish. Indeed, sometimes an emergency call isn't just helpful- it's mandatory when convicted of another crime.

The best way to get an honest review of an attorney is to talk to a past client. If you are lucky, you can go off the advice of your friends to see which attorneys will actually help your case, and which will instead just see you as a walking wallet full of cash. Personal feedback is the best option in weighing your possibilities, but not always possible.

Final Thoughts

Being convicted of a crime can have huge repercussions on your life. You won't want to trust just anyone with your future in employment and happiness. Remember these tips to keep your odds of success in the case running high.
