Abstract:
A system for standard positioning service (SPS) and precise positioning service (PPS) cooperative operation is disclosed. In one embodiment, a PPS receiver is utilized to process a PPS data portion of a positioning signal. In addition, an SPS receiver is utilized to process an SPS data portion of the positioning signal. Furthermore, the PPS receiver and the SPS receiver are communicatively coupled such that the PPS data portion from the PPS receiver is cross-validated with the SPS data portion from the SPS receiver thereby corroborating the accuracy of the positioning signal.
