Question

We can map information contained in GUS GAS GPS GIS

Answer 1

Correct answer choice is:

C. GPS.

Explanation:

The Global Positioning System (GPS) is a system of around 30 satellites revolving around the Earth at an elevation of 20,000 km. Once it has data on how far apart at slightest three satellites are, your GPS receiver can pinpoint your position applying a method termed trilateration.

GPS Mechanism:

Firstly, the signal of time is transmitted from a GPS satellite at a delivered position. Consequently, the time interval between GPS time and the point of time clock which GPS receiver acquires the time signal will be measured to produce the range from the receiver to the satellite. The equivalent method will be performed with three different possible satellites. It is likely to estimate the location of the GPS receiver from the length from the GPS receiver to three satellites.

Answer 2

Answer:

"GPS"

Explanation:

GPS; Global Positioning System, and originally Navstar GPS, is a system that allows the determination of the entire position of any object (a person, a vehicle) with an accuracy of up to centimeters (if differential GPS is used), although the usual ones are few meters of precision. The system was developed, installed and used by the US Department of Defense. UU To determine the positions in the balloon, the GPS system uses 3 or more satellites and uses trilateration. In practice, 4 or more satellites are normally required to determine the position with some precision.
