Abstract
Navigation is examined using information that is presently known about the modernized GPS signal. Although the full signal has not yet been fielded, its technical description can be used to predict its performance. The ranging accuracy of the new signal is compared to the classic signal. First, the signals are described. The correlation processes and consequent tracking accuracies are then determined. Finally the effect of multipath on the M-code is examined as a method to assess the future performance of the broadcast ephemeris. In most cases the performance of the modernized GPS signal is improved over the classic GPS signal, implying that it would be advantageous for receivers to employ it.
