How many satellites needed to get a position?
Typically, three satellites are needed to determine a 2D position (latitude and longitude), while four satellites are needed to determine a 3D position (latitude, longitude, and altitude) using GPS technology.
WHAT is the difference between satrack and gps?
Sattrack is a system used to monitor satellites' positions and orbits, while GPS (Global Positioning System) is a network of satellites that provides location and time information to GPS receivers on Earth. In essence, sattrack is more specific to tracking satellites, whereas GPS is a broader system for determining precise location on Earth.
What layer of the atmosphere do GPS satellites orbit in?
SatellitesSatellites orbit in outer space, not in the earth. They are sent to outer space where the gravitational pull of the earth pulls them around, just as the earth is pulled around the sun in a similar manner. The layer is the exosphere. It greatly depends on what the satellite is for and who owns it how far up it orbits. Imaging satellites need to be close to the Earth, so they orbit about 130 miles up. Communications satellites are generally at 23,000 miles up. GPS satellites are up about 13,000 miles.
Examples of artificial satellites?
First was sputnik, but anything from the Direct TV and XM radio satellites and telecommunication, GPS to the International Space Station are artificial satellites in Earth Orbit. There are artificial satellites currently in orbit around other planets as well.
What is the abbreviation for the use of satellites to find your latitude and longitude?
The abbreviation is GPS, which stands for Global Positioning System.
How many satellites do you need to have a full GPS signal?
A minimum of 4 satellites is needed to obtain a full GPS signal. These satellites are used to triangulate your position accurately on Earth.
Do you need a susbscrption to use a gps?
No. GPS Satellites are free to receive.
Do you need to be connected to the internet to use the GPS?
No as GPS is obtained from satellites.
What do gps satellites find?
GPS satellites do not 'find' anything, that is not their purpose.
How many satellites does the receiver need to be fixed on in order to know it's position?
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.
What type of orbit is used by gps satellites subsynchronous or sunsynchronous?
Geostationary satellites are the ones used for GPS satellites.
How many GPS satellites are required to triangulate a plan-form position?
You would need at least three GPS satellites to pinpoint your location. However, you would need a fourth to also identify your elevation.
Do GPS satellites need to be recalibrated for time corrections?
No, GPS satellites do not need to be recalibrated for time corrections. The atomic clocks on the satellites are highly accurate and stable, and any necessary adjustments can be made remotely from the control segment on the ground.
How many gps transmitter can be connected with one gps receiver?
One GPS satellite can serve an unlimited number of receivers, if they have unobstructed line-of-sight. GPS receivers need to see a minimum of 4 satellites in order to calculate an accurate 3-dimensional position. Almost all of them have the ability to work with up to 12 satellites simultaneously, if they can see that many.
What are two names of satellites?
GPS IIA-1 NAVSTAR 1 (Both GPS satellites)
How many GPS Satellites does the US Deptartment of Defense have?
There are currently 30 healthy GPS satellites in orbit.
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.
