Uncorrelated samples of GPS carrier phase can be measured at a high rate in a tracking loop or via open-loop tracking. The high-rate carrier phase estimates from both approaches are expected to be equivalent to each other. However, the practical implementation of the tracking loop could cause a small difference in the measurement, which may become substantial when there is residual or transient error...
This paper describes GPS carrier phase (CP) multipath characterization and error reduction techniques and their application in single aircraft relative positioning. In particular, the single aircraft relative positioning scenario has applications for high-accuracy multi-sensor stabilization where CP multipath is a major error source that limits system performance. We will briefly review the requisite...
