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.

Where are GPS satellite signals processed?
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.
What do Satellites have to do with cellphones?
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.
What are the name of satellites of planet Mercury?
There are no known satellites of Mercury.
What is a geostationary satellite?
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.
How does a GPS satellite work with a GPS device?
signals from at least 3 satellites send signals to and receive signals from the gps which are then triangulated to give the exact position of the GPS unit. Most GPS units are receive only. That is they must receive positional and timing information from the GPS satellite constellation. The internal processor them computes your position based upon this data(triangulation). Generally receiving data from three or more satellite's is needed to be produce a good fix (your position) but this is also dependent upon the geometry of the satellites. The best fixes are obtained when you have signals from three or more satellites which are geometrically separated by 45 degrees.
Name and position of satellites are in the sky?
There are thousands of satellites; most of them change their position rather fast.There are thousands of satellites; most of them change their position rather fast.There are thousands of satellites; most of them change their position rather fast.There are thousands of satellites; most of them change their position rather fast.
How many satellites needed to get a position?
You need 4 to locate a position. There are 24 satellites in use in the sky with 8 spares.
At least how many satellites are needed to calculate the position?
It takes at least 3 satellites.
What do you have to have to make a GPS work?
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.

What do the managers of Global Positioning System most regularly correct for?
Time and position of the satellites.
Can you see satellites on a map?
There are satellite tracking feeds available to show the current position of satellites in 3-D on Google Earth. See related links below for details.
How does a GPS function work?
There are many satellites that are positioned in the lower atmosphere. They relay their position by transmitting a "beacon" signal to a ground or water based station. When you have 3 or more satellites using a beacon, you can triangulate your position by using simple trigonometric geometric calculations. If you can obtain more satellites, then your position is more accurate. Many devices limit the number of satellites that they try to pick up the beacon because of the battery drain. Most devices on the common market are good to about 30 meters or 100 ft. GPS satellites are maintained in orbit by using very small thrusters and powered by solar and/or extra powerful batteries.
How have satellites change the way you live?
You can telephone people and watch tv
What can generally be defined as a change in position?
Movement is a change in position
Why earths satellites are not attracted by sun?
They are, but are held in Earth's orbit because of their much closer position to the Earth.
How many satellites does Tom Tom GPS use?
Every GPS unit needs a minimum of four (4) satellites to compute a 3-dimensional position, and performs more accurate calculations with more satellites. I think my TomTom is capable of using 12 simultaneous satellites if it can see that many. Yours may be different.
