  • System for standard positioning service and precise positioning service cooperative operation
    Publication number: 20080001813
    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.

  • Method for standard positioning service and precise positioning service cooperative operation
    Publication number: 20050038601
    Abstract: A method for standard positioning service (SPS) and precise positioning service (PPS) cooperative operation is disclosed. In one embodiment, a positioning signal is received. A PPS data portion of the positioning signal is acquired with a PPS receiver. An SPS data portion of the positioning signal is acquired with an SPS receiver. The PPS receiver and the SPS receiver are then communicatively coupled. The PPS data portion from the PPS receiver is then cross-validated with the SPS data portion from the SPS receiver, wherein the cross validation of the PPS data portion and the SPS data portion provides information about the validity of the positioning signal.
