A position determination device includes at least one processor, a first communication device for transmitting a signal in a first frequency band, a second communication device for communicating with a vehicle mobile device using radio waves in a second frequency band different from the first frequency band. The at least one processor acquires first data indicating the reception state at the vehicle mobile device of a signal from the first communication device, acquires second data indicating the distance from the second communication device to the vehicle mobile device, and determines the location of the vehicle mobile device based on the acquired data.
