Best Answer

You would need at least three GPS satellites to pinpoint your location. However, you would need a fourth to also identify your elevation.

There are currently Twenty Four Satellites orbiting the Earth, three are needed to provide latitude and longitude. To obtain altitude, four are needed.

How many satellites do you need for a GPS to find your position on earth?

There are 24 satellites in the United States GPS system that are active. There are 6 more that are "asleep" and saving power until they are activated to replace one of the 24 satellites that has to be taken off line for maintenance, damage, and so forth.The Russians also have roughly that number of satellites in their GLONASS system.Europe is deploying satellites in its Galileo positioning system.Japan has or will launch its first satellite in its QTZZ positiong system.There are also about 4 satellites in WAAS, the Wide Area Augmentation System that makes GPS more accurate. Europe's version of this is EGNOS, or European Geostationary Overlay Service. It has 4 or 5 satellites.


How many geo stationary satellites are needed to cover the earth at a time?

Please be a little more precise in your meaning when you say "cover" the Earth. For radio or TV communications, three satellites in geosynchronous orbit will be visible from any inhabitable locale on the planet. (The polar regions aren't really "inhabitable", and aren't visible from GEO. ) For navigational purposes, more are required. The GPS system requires line-of-site to FOUR satellites at one time in order to give a good "fix" of your position; the USAF uses 27 satellites to accomplish this, anywhere on the Earth.


What is a function of a GPS receiver?

GPS receiver will be located at the centre of the satellite zones.....It will be synchronized with all satellites....Hence it can receive signals from any one of the satellite at a time....Remaining signals which are transmitted from other satellites are ignored..


Do you have to subscribe to gps service?

The signals that a GPS receiver or Sat Nav system uses to calculate its position are broadcast freely and globally by the GPS satellites orbiting earth 20,000Kms away. As there is no way for the GPS satellites to know who or what is receiving or using the signals that they broadcast, it would be impossible to charge people for their use. Much like free to air TV or radio. Subsequently, the GPS service is free. The hardware required to use it however will cost you.

What is RF tracking as compared to satellites?

I'm assuming you are talking about GPS when you say "satellite." RF tracking can be directional. It takes three RF receiver stations to triangulate the position of an RF transmitter and is usually less accurate than GPS. RF is also more limited by range, so the RF tracking stations are usually required to be mobile depending on the strength of the transmission signal.

What is the minimum amount of satellites required to ascertain longitude latitude and height?

Latitude/longitude . . . . . 3 satellites Elevation . . . . . 4 satellites But the more birds, the better the accuracy of the position data. Also, if you paid less than $1,000 for your instrument, then don't believe anything it tells you for elevation.

What is the navigation satillite function?

Satellites used for Global positioning, send clock signals back to the earth, along with identity signals. The timing of the clock signals are very accurately controlled. The receiver uses the clock signals and by applying mathematical processes and comparing with an on board almanac, calculates the receiver's position. At least three signals from different satellites are required to fix a position. More signals then add to the accuracy.
