摘要：

For low power GNSS (Global Navigation Satellite System) signals, the most powerful processing approach is the long coherent integration of the signal. This approach supposes that the phase of the GNSS signal is accurately estimated. Unfortunately, the phase measurements may be very noisy and subject to cycle slips. The aim of this paper is to propose a new fusion estimate that can detect cycle slips in the signal and that takes the circular nature of the phase measurements into account. We propose to fuse the phase observations obtained on the two multiplexed channels of the GPS (Global Positioning System) L2C signal. We experimentally compare the accuracy obtained for the mono-channel GPS L1 signal and for the multi-channel GPS L2C signal.
