Some do. There are two types of orbits we use regularly. The first is Geosynchronous That is the satellite changes speed at exactly the same rate as our planet, so it appears that it doesn't move.
The second we use allot is polar orbits. This is a lower orbit that allows the satellite to see every point on the planet at regular intervals. We use these as spy satellites and for places like Google maps.
It is possible to change a satellite's position by using other satellites in the same orbit, as landmarks. This is done by entering the four digits of the landmark satellite into a computer and then programming the satellite to change to that direction.
Natural satellites don't usually change position because for mankind to alter their orbiting path would be interfering. they occasionally change position due to their own cause.
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.
with calls themselves, nothing. however all current cell phones have a GPS receiver that picks up and decodes the signals from GPS satellites so their position can be accurately determined for emergency 911 calls.
There are no known satellites of Mercury.
Geostationary is the moving orbit in the plane of the equator. Geostationary satellites are 22,300 miles above the Earths surface, and remain stationary at a fixed point. Weather and communication satellites are examples of geostationary satellites.
Triangulation of satellites requires three satellites that bank of one another simultaneously.

Typically, three satellites are needed to determine a 2D position (latitude and longitude), while four satellites are needed to determine a 3D position (latitude, longitude, and altitude) using GPS technology.
It takes at least 3 satellites.
A GPS receiver typically needs signals from at least 3 satellites to calculate a 2D position (latitude and longitude) and 4 or more satellites for a 3D position (latitude, longitude, and altitude). The receiver uses the signals from multiple satellites to triangulate its position on Earth.
GPS needs signals from at least 4 satellites to accurately calculate a 3D position on Earth. By receiving signals from multiple satellites, the GPS device can triangulate its position using the known positions of the satellites. This allows for highly accurate location determination.
GPS devices receive signals from several Global Positioning Satellites, which orbit the earth. The device uses the difference in timing from the signals to calculate its own position. I don't remember, but I think you can get a position with signals from 4 satellites, so you would need to have a clear signal from the satellites in order for the device to calculate its position.
A minimum of 4 satellites is needed to obtain a full GPS signal. These satellites are used to triangulate your position accurately on Earth.
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.
A GPS receiver gets its signal from a network of satellites orbiting the Earth. These satellites continuously transmit signals that the GPS receiver uses to calculate its position and determine accurate time information. By receiving signals from multiple satellites, the GPS receiver can triangulate its position with high precision.
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.
Time and position of the satellites.
Atomic clocks or rubidium clocks are commonly used in satellites for precise timekeeping. These clocks are highly accurate and stable, allowing satellites to track their position and perform various operations with precision.
