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.

Claim (Index 1):
A satellite signal reception apparatus that receives a satellite signal from a satellite, the satellite signal reception apparatus comprising:\n a satellite antenna that receives the satellite signal; a satellite orbital information collection unit that collects and outputs orbital information of the satellite; a peripheral environment spatial information collection unit that collects and outputs spatial information for a peripheral environment of an installation position of the satellite antenna; a positional information collection unit that collects and outputs positional information for the installation position of the satellite antenna; and a signal correction unit that performs a determination process to determine, based on the orbital information, the spatial information, and the positional information supplied from the satellite orbital information collection unit, the peripheral environment spatial information collection unit, and the positional information collection unit, whether a satellite associated with the received satellite signal is in a directly viewable (Line-of-Sight: LOS) state or in a non-directly-viewable (Non-Line-of-Sight: NLOS) state from the installation position of the satellite antenna, and that performs a correction process on a satellite signal from a satellite in an NLOS state, on the assumption that the satellite signal is a reflected wave.
