Abstract
A navigation satellite signal reception apparatus includes a satellite antenna; a satellite orbital information collection unit that collects orbital information of a navigation satellite; a peripheral environment spatial information collection unit that collects spatial information for a peripheral environment of an installation position of the satellite antenna; a positional information collection unit that collects positional information for the installation position of the satellite antenna; and a signal correction unit that performs a determination process to determine whether a navigation satellite associated with the received satellite signal is in a directly viewable state or in a non-directly-viewable state from the installation position of the satellite antenna, and that performs a correction process on a satellite signal from a navigation satellite in an NLOS state, on the assumption that the satellite signal is a reflected wave.
