In this article here two words are used first is GPS and the second is SATELLITE, first, we know what is satellite.
What is Satellite
A satellite is an object in space that orbits or circles around a bigger object. There are two kinds of satellites: natural satellite and artificial satellite.
1. Natural Satellite.:- In space, about 53 satellites but the big example of the natural satellites is earth and moon. The earth is orbiting the sun and the moon is orbiting the earth.

2. Artificial Satellite:-An artificial satellite is an object that is made by man and launched by using rockets. There are currently over a thousand active satellites orbiting the Earth. The size, altitude, and design of a satellite depend on its purpose.

GPS Satellite also an artificial satellite, GPS satellite is used for satellite navigation and give autonomous geo-spatial positioning. The GPS satellite consists of electronic receivers to determine their location with longitude, latitude, and altitude with high precision using time signals. Minimum four satellites required for receiving the three-position coordinates and clock deviation from the satellite time. Each GPS satellite is continuously transmitting the radio signals containing the current time and data about its position. the speed of radio waves is constant and independent of the satellite speed, the time delay between when the satellite transmits a signal and the receiver receives it is proportional to the distance from the satellite to the receiver. A GPS receiver monitors multiple satellites and solves equations to determine the precise position of the receiver and its deviation from true time.
HOW DOES GPS WORK WITH SATELLITE
There are three segments required with working GPS with the satellite.
1. Space Segment.
2. Control Segment.
3. User Segment
1. Space Segment.
2. Control Segment.
3. User Segment
1. The space segment contains 24 satellites in 12 hours, near-circular orbits at an altitude of about 20000 with an inclination of orbit 55°.At least 4 sett elite views on the earth's surface in 3d mode.
2. Control Segment:- It consists of three-part
A. Master Control Station
B. Monitor Status
C. Upload Status.
3. User segment:- User segment contains an antenna, receiver, a data processor with software, and a control/ display unit. GPS receiver measures the range, phase, and other data using navigation signals minimum satellites and computes 3D position, velocity, and system time.
