An artist's impression of what the Mayak satellite could look like once in orbit. The proposed 'Mayak' satellite would have a huge pyramid-shaped reflector to make it easily visible in the night sky. A group of Russian engineers has raised over Â£17,000 to launch a reflective satellite which would be one of the brightest objects in the night sky.
A GPS satellite is a satellite used by the NAVSTAR Global Positioning System (GPS). The first satellite in the system, Navstar 1, was launched February 22, 1978. The GPS satellite constellation is operated by the 50th Space Wing of the United States Air Force. The GPS satellites circle the Earth at an altitude of about 20,000 km (12,427 miles) and complete two full orbits every day.
