Are GPS in geostationary orbit?

The Global Positioning System (GPS) is a constellation of about 24 artificial satellites. The GPS satellites circle the Earth at an altitude of about 20,000 km (13,000 miles) and complete two full orbits every day. The GPS satellites are not in a geostationary orbit, but rise and set two times per day.

Is the ISS geosynchronous?

The International Space Station and the Hubble Space Telescope are both in LEO. A geostationary or geosynchronous orbit is located at an altitude of 36,000 km, and takes a lot more energy to reach than LEO. At this higher altitude it takes the satellite a full 24 hours to orbit the Earth.

Why there is only one geostationary orbit?

A satellite that stays above one place on the Earth's surface has to sit above the Equator. The satellite sits at one height due to a balance of two factors, one depending on the speed in orbit and one on the gravitational field. Both of these depend on the radius of orbit, but in different ways.

What are types of artificial satellites?

  • There are essentially three types of Earth orbits: high Earth orbit, medium Earth orbit, and low Earth orbit.

  • What is geostationary satellite class 9?
