Abstract:
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 same code phase and carrier frequency signal space, the system comprising correlators for defining the code phase and carrier frequency 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 code phase and carrier frequency signal space, the first and second signals having the same carrier frequency and code phase defining the code phase and carrier frequency signal space, the first and second signals having different code phase offsets and carrier frequency offsets when not overlapping each other but remaining within the code phase and carrier frequency signal space, a detector for detecting the first and second signals in the code phase and carrier frequency signal space when not overlapping in the code phase and carrier frequency signal space, and a tracker for concurrently tracking the first signal and second signal in the code phase and carrier frequency signal space when the first signal and the second signal are and are not overlapping in the code phase and carrier frequency signal space.
