摘要
The method involves determining a set of energies from a set of advanced monitoring correlators (VE1-VEC) by considering a received signal and advanced replica signals with respect to replica signals (S-RE, SRP, S-RL). Energies issued from correlation results obtained by the advanced monitoring correlators are compared to a threshold to monitor that a correlation peak is relative to a direct path of the received signal. The threshold is determined based on estimation of output noise energy of correlators and a probability of false alarm allocated to a detector. An independent claim is also included for a satellite positioning receiver comprising a set of advanced monitoring correlators.
