Mars has two natural satellites. Phobos is the nearest and orbits Mars in just a few hours. It rises in the west and sets in the East. Demios is further out and only takes sl â¦ ightly longer to go round Mars than it takes Mars to turn on it's axis so it spends several days climbing up the sky.
Many modern GPS receivers use a combination of both GPS and the Russian GLONASS satellites for improved coverage and accuracy. The GPS system currently has 31 active satellites in orbits inclined 55 degrees to the equator. The satellites orbit about 20,000km from the earth's surface and make two orbits per day. The orbits are designed so that there are always 6 satellites in view, from most places on the earth. GPS uses a lot of complex technology, but the concept is simple. The GPS receiver gets a signal from each GPS satellite.
