Positioning apparatus

A positioning apparatus comprising at least one processor configured to implement:

• a satellite positioning information receptor that receives positioning information from positioning satellites;
• a ground reinforcement information receptor that receives positioning reinforcement information from a ground base station;
• a first own position calculator that calculates a first own position, based on the positioning information and the positioning reinforcement information of the ground base station;
• a satellite reinforcement information receptor that receives positioning reinforcement information from the positioning satellite;
• a second own position calculator that calculates a second own position based on the positioning information and the positioning reinforcement information of the satellite;
• a driving mode receptor that receives a driving mode signal which indicates whether or not a driving mode of an own vehicle is an automatic driving mode, from an automatic driving apparatus of the own vehicle which is an arithmetic object of an own position;
• an own position selector that determines either the first own position or the second own position to be used, based on the driving mode;
• and
• an own position outputter that outputs the first own position or the second own position which is determined to be used by the own position selector, as a final own position.
