Abstract
A GNSS receiver includes at least two antennas, a satellite direction acquisition module, an estimation module, and a determination module. A satellite direction acquisition module acquires the direction when viewing the satellite corresponding to the GNSS signal received by the antenna based on the satellite orbit information. The estimation module estimates the arrival direction of the GNSS signal on the basis of the difference in timing when the GNSS signal is received by the plurality of antennas. The determination module compares the direction in which the satellite is viewed from the antenna with the arrival direction estimated by the estimation module to determine whether the GNSS signal received by the antenna is a direct GNSS signal based on a direct wave from the satellite or an NLOS GNSS signal.
