Abstract:
Described herein is a receiver for a navigation system, which receives a navigation signal modulated with a pseudorandom sequence along a line-of-sight path and reflected paths. The receiver includes a delay-locked loop, which generates a local sequence, and a first correlator and a second correlator, which operate in open-loop mode and generate a first correlation signal.
