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

What is the minimum number of operationsl navstar satellites required for the space segment of gps?
A minimum of 24 operational Navstar satellites are required for the GPS system to work effectively. These satellites are strategically positioned in orbit to ensure global coverage and accurate positioning for GPS receivers on Earth.
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 it necessary to observe a minimum of four gps satellites to define position?
The GPS receiver measures the distance from it to a GPS satellite. Then it measures the distance to another GPS satellite. The location is somewhere on a line made up of the millions of plaes that these two distances cross each other. A third satellite distance is required to find out where your GPS receiver is, somewhere on that line.This process is called "Trilateration" (Three distances). (Not triangulation).If you want to know how high you are above sea level, you need a distance from a fourth satellite.
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..
How many points are neede to triangulate an earthquake?
To triangulate the epicenter of an earthquake 3 points are required.
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 number of triangles required to triangulate an hendecagon?
9 (two less than the number of vertices in the polygon).
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.
Minimum satellites required for a GPS system?

What is the minimum number of artificial satellites required for communication through the globe is?
3 GEO Satellites located at 120 degrees are required to cover whole of the earth.
How many gps satellites are required to pinpoint your location on earth surface?
At least four GPS satellites are required to pinpoint a location on Earth's surface accurately using trilateration. Three satellites are needed to determine a two-dimensional position (latitude and longitude), while the fourth satellite provides the altitude component.
What is the minimum number of operationsl navstar satellites required for the space segment of gps?
A minimum of 24 operational Navstar satellites are required for the GPS system to work effectively. These satellites are strategically positioned in orbit to ensure global coverage and accurate positioning for GPS receivers on Earth.
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.
