Detailed explanation-1: -To accomplish this, each of the 31 satellites emits signals that enable receivers through a combination of signals from at least four satellites, to determine their location and time.
Detailed explanation-2: -It takes four GPS satellites to calculate a precise location on the Earth using the Global Positioning System: three to determine a position on the Earth, and one to adjust for the error in the receiver’s clock.
Detailed explanation-3: -GPS provides full coverage with signals from a minimum of 4 satellites available to the user, at any place on the earth. Q. A GPS relies on the signals from a system of 24 satellites placed at different orbits around the Earth.
Detailed explanation-4: -As we noted above, the GPS receiver needs 4 satellites to work out your position in 3-dimensions. If only 3 satellites are available, the GPS receiver can get an approximate position by making the assumption that you are at mean sea level.
Detailed explanation-5: -Not enough satellites With fewer satellites the amount of uncertainty and inaccuracy increases. With less than 4 satellites, many GPS receivers struggle to produce accurate location estimates, and will report “GPS signal lost” at points during the route.
