Thursday, May 29th, 2008Understanding The Basics Of GPS by Beau Hooks
The GPS (Global Positioning System) has been fully functional for nearly two decades. GPS consists of 27 satellites positioned in a medium earth orbit. A satellite is considered to be in medium earth orbit when it is 35,000 kilometers above the Earth’s surface, roughly 22,000 miles. The first experimental satellite was launched in 1972. It was not until 1995, 23 years after the launch of the first experimental satellite, that GPS bore fruit as a fully function satellite tracking system. Even then the system was restricted to military and airline industry use.

Global Positioning Is Free - How GPS Works And Why You Should Use It
Thursday, November 22nd, 2007As most of you know GPS is an acronym for Global Positioning System, but how does global positioning really work?
The Global Positioning System is a satellite-based navigation system, consisting of more than 20 satellites and several supporting ground facilities, which provides accurate, three-dimensional position, velocity, and time, 24 hours a day, everywhere in the world, and in all weather conditions.
The Global Positioning system consists of three main components:
1. GPS Ground control stations.
The Future of GPS
Thursday, December 28th, 2006The use of Global Position System (GPS) has become quite diverse from automobiles, mobile phones, tourist facilities, city maps, and even pet collars. GPS works through a network (often called constellation) of 27 satellites that move around the Earth in geo synchronous orbit. These satellites exchange relative data to fix the position of one particular object on the surface. Similar to the Internet, the technology was original implemented for military use in order to help precise control of troops as well as getting accurate information about enemy troops and armament placement and movement. And like the Internet it was soon the commercial use that would dominate global reliance on GPS.
GPS Technology
Monday, November 6th, 2006GPS, or Global Positioning System, is the only practical satellite navigation system available today. There are more than twenty four GPS satellites orbiting the Earth and they all broadcast precise signals in radio waves that permit GPS receivers (GPSr) to mark the exact position of any object on the surface of the earth in terms of latitude, longitude, and altitude. These signals work in all weather and round-the-clock all over the world, that is why they are called Global.
