Final answer:
Differential Correction does not use data from only one GPS receiver; it compares data from a rover GPS receiver and base station to reduce positional errors, making statement d) incorrect.
Step-by-step explanation:
The statement that is NOT true for Differential Correction is: d) Uses data from only one GPS receiver. Differential Correction is a technique used to improve the accuracy of GPS data by correcting the signal errors. It involves the comparison of two sets of data, one from a rover GPS receiver and the other from a base station, which is at a known location. This technique uses data from two or more receivers to reduce positional errors and relies on base stations to calculate range errors.
