DEVICE FOR RECEIVING SATELLITE SIGNALS INCLUDING A PHASE LOOP WITH DELAY COMPENSATION

摘要

The invention pertains to the field of devices for receiving satellite radio-navigation signals, the signals being transmitted at a carrier frequency, said device including at least means for generating a local signal at a local frequency and a tracking device including a feedback loop, or so-called carrier loop, for the phase control of the local frequency onto the carrier frequency, said loop including a hardware portion and a software portion. The software portion carries out the functions of discriminating the correlated signal phase and filtering said phase. In the different devices of the invention, the software portion further includes correction functions substantially based on the linear variation coefficients between the local phases flocale provided after each elementary calculation cycle. The device of the invention increases the loop band and the dynamic stability without modifying the pre-detection band and the workload of the software.
