This is where the Shuttle and ISS conduct their operations. One complete orbit in LEO takes about 90 minutes. Satellites that seem to be attached to some location on Earth are in Geosynchronous Earth Orbit (GEO). These satellites orbit about 23,000 miles above the equator and complete one revolution around the Earth precisely every 24 hours. Satellites headed for GEO first go to an elliptical orbit with an apogee about 23,000 miles.
Velocity Relative to the Earth. Relative to the Earth, GPS satellites orbit twice in a sidereal day, the length of time the stars (instead of the sun) take to return to the original position in the sky.Since a sidereal day is about 4 minutes shorter than a solar day, a GPS satellite orbits once every 11 hours and 58 minutes.With the Earth rotating once every 24 hours, a GPS satellite catches up to a point above the Earth approximately once a day.elocity Relative to the Earth.
