Because they can't provide worldwide coverage. To cover near-polar areas, inclined orbits are necessaries. Since the geostationary orbit must lay on the equatorial plane, it doesn't suit to fit GPS requirements.

GPS satellites are placed in medium Earth orbit (MEO) rather than geostationary orbit because MEO offers better coverage and accuracy for global positioning. Geostationary satellites, which orbit at a fixed point above the equator, would not provide adequate coverage at high latitudes. Also, geostationary orbits are higher up, resulting in longer signal travel times which can reduce GPS accuracy.

Is international space station closer to Earth than the weather satellites and GPS satellites in miles?
It depends on which satellite you are talking about. However YES, it is closer than any geostationary weather satellite and it is closer than any GPS satellites.
How many satellites do you need for a GPS to find your position on earth?
A GPS receiver typically needs signals from at least 4 satellites to accurately calculate your position on Earth. By triangulating the signals from multiple satellites, the GPS receiver can determine your location with high precision.
what does the phrase gps caddie meaN?
A GPS stands for Global Positioning Satellite and is a device which uses satellite location to determine your position. A caddie is a device which is a container or carrier for another item. As such, a GPS caddie is an item which holds a GPS.
What is the transmission media of GPS?
satellite signals
How many kinds of GPS?
Global Navigation Satellite System.- Global positioning system (USA)-Globalnaya Navigatsionnaya Sputnikovaya Sistema (Russia)-Galileo (Europe)-QTZZ (Japan)SBAS Satellite Based Augmentation System. (Improves precision for airplanes and ground stations of various kinds.)-WAAS Wide Area Augmentation System. (An SBAS developed by the US for precision in landing airliners. Is also used with ground GPS receivers to improve precision)-EGNOS European Geostationary Navigation Overly Service (An SBAS developed in Europe)

Why does a satellite travel over different parts of the earth?
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.
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.
What type of orbit is used by gps satellites subsynchronous or sunsynchronous?
Geostationary satellites are the ones used for GPS satellites.
Are G.P.S and Geo-stationary satellites are different?
Yes, GPS and GeoStationary satellites are two different things.
How does gps calculate its positinon?
by satellite.

Where can I find information about gps satellite tracking?
Here's a link to a website that offers a lot of interesting information to learn about GPS satellite tracking. http://www.edu-observatory.org/gps/tracking.html

How do you use GPS in a sentence?
GPS is an abbreviation of Global Positioning System, a receiving system that utilises regulated signals sent from geostationary satellites to triangulate its location upon the Earth.
What is the transmission media of GPS?
satellite signals
List a few common application areas for each orbits level satellite systems?
Low Earth Orbit (LEO): Earth observation, remote sensing, satellite communication. Medium Earth Orbit (MEO): Global positioning system (GPS). Geostationary Orbit (GEO): Weather monitoring, telecommunications, television broadcasting.
