GPS stands for Global Positioning System and was originally developed for use by U.S. military and is operated by the UP Department of Defense. This system consists of 24 satellites, these satellites are 12,000 miles before us, we are constantly moving in a precise orbit, has an atomic clock and are powered by solar energy. Do you have a battery backup so that it will continue to operate in case of a solar eclipse, and everyone must keep a small rocket and satellite in its orbit. L 'first satellite was launched in 1978 and it was not until 1994, when there were a total of 24 satellites. Each satellite has a duration of about 10 years, new satellites are built and continuously. Each satellite weighs about 2,000 kg and is 17 meters wide, when the solar system be expanded. In 1980, GPS has been available to the public, and although it is still waiting for the SU Department of Defense, there is no fee for its use byPublish.
These 24 satellites orbiting the earth twice a day and constantly sends the position of the satellite. A GPS system can tell what is a satellite by comparing the time difference between when a signal is sent and the time it was received, the time it takes the signal from the receiver to be received, as far as the satellite. If the signal from three GPS satellites can calculate latitude and longitude. The height can be determinedif the GPS signals from four satellites.
GPS navigation can be used in the car through traffic from day to day or the pursuit of a fleet of vehicles. Not only can you make a driver with a GPS guidance of the center, where the vehicle and the vehicle speed. GPS can be used during the leave for activities such as hiking, camping or hunting.
