Improved sensitivity to reflected GNSS signals

摘要

Examples for improving sensitivity to reflected GNSS signals are presented here. An example may include a receiver identifying a particular positioning signal that was reflected from a reflective plane before it reached the receiver. The receiver can be on the move. The example may also include determining a reflected satellite position for a satellite that has sent the particular positioning signal,based on the identification of the specific positioning signal. The reflected satellite position can be determined by mirroring a position of the satellite around the reflecting plane. The example may also include determining a direction vector to the reflected satellite position for the satellite and performing a coherent integration over a threshold time period to increase a signal-to-noise ratio for the particular positioning signal based on the direction vector to the reflected satellite position.
