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.
