Consider the following statements :
- 1GPS uses signals from a network of satellites to determine a position on the Earth.
- 2The 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?
general-scienceinformation-technology
- A1 only
- B2 only
- CBoth 1 and 2
- DNeither 1 nor 2
Explanation
GPS works by receiving timed signals from a constellation of satellites and computing position from them — statement 1 is correct. Statement 2 is wrong: the receiver uses trilateration from at least three–four satellites to fix latitude, longitude and altitude; it does not determine position merely 'by the use of latitude'. Hence only statement 1 is correct.
