Abstract
Methods and systems for resolving the lock point ambiguity for the GPS receiver are disclosed. The method involves generation of the absolute lock point data bit by the reference station receiver, transmission of the absolute data bit to the rover receiver, and comparison between the raw lock point data with the absolute lock point data bit in the rover receiver. The system employs the reference station receiver, the rover receiver, and the communication link.
