1. A system for tracking a first signal in a code phase and carrier frequency signal space in the presence of a second signal in the code and carrier frequency signal space, the system comprising correlators for defining the signal space having a field of view encompassing the presence of the first signal and the second signal when not overlapping each other within the signal space, a detector for detecting the first and second signals in the signal space when not overlapping in the signal space, and a tracker for concurrently tracking the first signals and second signal in the signal space when the first signal and the second signal are and are not overlapping in the signal space.
