Consider the following statements : 1. GPS uses signals from a network of satellites to determine a position on the Earth. 2. The GPS receiver calculates the distances from satellites to triangulate the exact location by the use of latitude. Which of the statements given above is/are correct?
1 only
Statement 1: The Global Positioning System (GPS) works by receiving timed signals from a constellation of satellites orbiting the Earth, using them to fix a user's position. This statement is correct.
Statement 2: The GPS receiver does not use "latitude" to fix a position; instead, it measures the time delay of signals from at least four satellites, converts this into distances, and uses the mathematical technique of trilateration (not triangulation, and not by using latitude directly) to compute the coordinates. This statement is incorrect.
Hence, the answer is 1 only.
