Gps Satellite Orbit Period

The period of a satellite is the time it takes it to make one full orbit around an object.
Gps satellite orbit period. The period of the earth as it travels around the sun is one year. The satellites in the gps constellation are arranged into six equally spaced orbital planes. Gps satellites fly in medium earth orbit meo at an altitude of approximately 20 200 km 12 550 miles. Orbits of the gps satellites distances are to scale the satellites orbit the earth with a speed of 3 9 km per second and have a circulation time of 12 h sidereal time corresponding to 11 h 58 min earth time.
As the satellite moves the earth rotates underneath it. Spacex aborted a scheduled launch of a us military gps satellite on friday night with just about two seconds left in the countdown. The galileo constellation comprises of 30 satellites placed in meo orbit with 10 satellites placed in each of 3 orbital planes at 56º nominal inclination distributed evenly round the equator the active constellation comprises of 24 satellites walker 24 3 1 including 6 spare satellites which can be moved to replace any failed satellite within the same plane thereby reducing the impact. Each satellite circles the earth twice a day.
It is the orbit used by the global positioning system gps satellites. The satellites have a speed of 3 9 km per second and a nominal period of 12 h sidereal time 11 h 58m 2 s repeating the geometry each sidereal day. In 24 hours the satellite crosses over the same two spots on the equator every day. This means that the same satellite reaches a certain position about 4 minutes earlier each day.
It is one of the global navigation satellite systems gnss that provides geolocation and time information to a gps receiver anywhere on or near the earth where there is an unobstructed line of sight to. The launch was scheduled for a 15 minute window that opened at 6. The global positioning system gps originally navstar gps is a satellite based radionavigation system owned by the united states government and operated by the united states space force. A satellite at this height takes 12 hours to complete an orbit.
You can calculate the speed of a satellite around an object using the equation. Gps svs are arranged on 6 planes each of them containing at least 4 slots. This orbit is consistent and highly predictable.
