Television service, weather prediction, global positioning system in my car.
A single satellite can only give you relative location. 3 satellites can give a 2-D positioning/location that includes longitude and latitude. 4 satellites can give a 3-D positioning/location that includes longitude, latitude and altitude. Only 4 satellites can give you absolute location.
Answer: 1.communication satellite 2.navigational satellite 3.weather satellite 4.millitary satellite 5.scientific satellite 6.satellite launches. It composed of 6 satellites...........i hope.....my answer can help you.....
it help support millitary activities 2-it help transfer telehone call over the ocean 4-they re used for exploring different planet 5-
Jupiter's 4 major moons, known as the Galilean satellites, are named Io, Europa, Ganymede, and Callisto. Io is an orange moon with an abundance of volcanic activity most likely caused by Jupiter's magnetic field. Europa is a cold, frozen ice moon and is also the smallest of the four. Ganymede is the largest and also is thought to have oceans. Callisto is the outermost moon (of the 4) and is covered with craters.

ther are 4 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.
3 different types
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.
For accuracy. 1 satellite can only tell you the distance from that satellite (a 3-d sphere around it). 2 satellites can only tell you what your distance from the two of them are(a 2-d circle between them). 3 satellites can give you 2 single points (1 one the surface of Earth, and one out in the middle of space, and they assume you are on Earth when using GPS). 4 satellites is to give extra accuracy on that point that you are at (4 times as accurate as 3 satellites).
The only thing your unit can tell from a single satellite is roughlyhow far you are from that satellite.But what you want is your location nailed down in 3 dimensions ...where you are left/right, where you are forward/backward, andwhere you are up/down. Your receiver calculates each of theseby comparing its distance from different satellites.And if you want all three dimensions, then you need a minimumof four (4) different satellites, not 3.

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 does not use internet, it uses a constellation of US Airforce satellites that transmit coded radio messages. A GPS receiver picking up the radio messages from at least 4 of these satellites can decode them and determine latitude, longitude, altitude, and UTC time with great accuracy.
probably not, as the Global Positioning System uses data from several satellites to calculate the receivers position. At any given time, there are usually at least 4 GPS satellites above the horizon from anywhere on Earth. Only interference on the GPS frequency can impair the accuracy.
There are currently 32 satellites, a gps system needs to receive a signal from at least 3 of them to function. Older systems only used 3-4 but new systems can use up to all 32 the more satellites that a system uses....the greater the accuracy.
