The system has at least 24 satellites located in six orbits at an altitude of about 20,000 km and ground control center monitoring stations located in different parts of the Earth. These satellites constantly emit encoded radio signal indicating their current position and the exact time. From the propagation delays of this signal, a special GPS receiver can calculate the position and velocity.
GPS was originally planned as a military project. The first test satellite was launched into orbit on 14 July 1974, and the first operational satellites of the future system was put on service on 22 February 1978. From 1978 to 1980, the number of satellites reached six. On 6 January 1980, the system was placed in operation for the first time. The last of the 24 satellites required for the full coverage of the globe was launched into orbit in late 1993, the and the system went on full alert 17 January 1994.
In 1983, due to a navigation error a South Korean civilian airliner with 269 people on board entered Soviet airspace and was shot down by a Russian fighter. Given the tragedy that could have been avoided, the U.S. president authorizes the use of the system for civilian purposes.
