This actually depends on the orbital radius, or distance from Earth's surface (or center). The further away the satellite is, the slower it travels to stay in orbit (related to Kepler's second law). A satellite that is really close to the atmosphere and barely in space needs to travel at about 7800m/s. A satellite can speed up and increase its tangential velocity to make its orbit bigger. A bigger orbit results in a lower speed. Interestingly, this means that an orbiter speeds up to slow down. Likewise, a satellite in a high orbit can fire its engines backwards to reduce its speed to get into a smaller, faster orbit, ultimately speeding up.
================================
In an orbit that's not a perfect circle, the speed in orbit is always changing.
The satellite moves faster when it's closer to the Earth, and slower when it's
farther out.
There are currently 30 healthy GPS satellites in orbit.
GPS signals are processed in the GPS unit and displayed, and they are also processed via three Global Position Satellites. All four units work together and process GPS signals (some to the satellites from the GPS, and some from the satellites to the GPS) to create an accurate position.
GPS satellites provide location and time information in all weather, anywhere on or near the Earth, where there is an unobstructed line of sight to four or more GPS satellites.
GPS
If you taking care of the GPS, It will last about 5 years
GPS satellites do not 'find' anything, that is not their purpose.
Geostationary satellites are the ones used for GPS satellites.
Navigation satellites move around Earth at an altitude of about 1,243 miles to 22, 223 miles and at about the same speed of rotation. These satellites are in what is called Medium-Earth orbits (MEO).
GPS devices receive data from satellites through signals transmitted by the satellites. The GPS receiver in the device then processes these signals to determine the device's location based on the time it takes for the signals to travel from the satellites to the receiver. This location data is then used to provide navigation information to the user.

A GPS works by satellites that are located in outer space. These satellites are connected with cameras that show the whole earth. You GPS and the satellites systems are working together to provide maps for you.
GPS technology uses signals from multiple satellites to determine the exact position of a device on Earth. By measuring the time it takes for signals to travel from the satellites to the device, GPS receivers can calculate the distance to each satellite. By combining these distance measurements from at least three satellites, the receiver can triangulate the device's position accurately.
Because most satellites are not 'geostationary'. A geostationary satellite orbits the Earth at the same speed that the Earth spins on its axis - such as the GPS grid, or TV relay satellites. Most satellites travel faster or slower than the Earth spins.
No. GPS Satellites are free to receive.
You can use a GPS anywhere the satellites shine.
