Satellite signal reception apparatus, satellite signal reception method and program therefor

A satellite signal reception apparatus that receives a satellite signal from a satellite, the satellite signal reception apparatus comprising:

• a satellite antenna that receives the satellite signal;
• a satellite orbital information collection unit that collects and outputs orbital information of the satellite;
• an omnidirectional-imaging unit that collects three-dimensional spatial information for a peripheral environment of an installation position of the satellite antenna and outputs the three-dimensional spatial information, where the three-dimensional spatial information includes data captured in all directions with respect to the 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 three-dimensional spatial information;
• and the positional information supplied from the satellite orbital information collection unit, the omnidirectional-imaging 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.
