This is approximately 17 000 mph 27 359 kph at an altitude of 150 miles 242 kilometers.
Gps satellite orbital velocity.
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 six orbits are tipped at 55 from the equator with four satellites per orbit see diagram.
This equation holds for any orbiting object where the attraction is the force of gravity whether it s a human made satellite orbiting the earth or the earth orbiting the sun.
The mathematical procedures of calculating the satellite s orbital parameters and the satellites coordinates will be focuses in section 3.
A closed form of an algorithm to determine a global positioning system gps satellite s position velocity and acceleration is proposed and an earth centred earth fixed ecef to earth centred inertial eci transformation result using the civil navigation cnav message is presented in this paper.
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.
Special relativity predicts that the frequency of the atomic clocks moving at gps orbital speeds will tick more slowly than stationary ground clocks by a factor of or result in a delay of about 7 μs day where the orbital velocity is v 4 km s and c the speed of light.
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.
Without gravity the satellite s inertia would carry it off into space.
Each satellite broadcasts radio waves towards earth that contain information regarding its position and time.
The orbital keplerian motion is defined by six orbital parameters.
To obtain the closed form of the gps.
The gps satellites are not in a geostationary orbit but rise and set two times per day.
Velocity of gps satellites global positioning system gps satellites travel approximately 14 000 km hour relative to the earth as a whole as opposed to relative to a fixed point on its surface.
Orbital velocity is the velocity needed to achieve balance between gravity s pull on the satellite and the inertia of the satellite s motion the satellite s tendency to keep going.
The speed can t vary as long as the satellite has a constant orbital radius that is as long as it s going around in circles.
Types of satellites ephemerides used to calculate satellites coordinate.
