Positioning device, method of controlling positioning device, and recording medium having program for controlling positioning device recorded thereon
First Claim
1. A positioning device which receives a satellite signal from a satellite positioning system (SPS) satellite and locates a present position, the positioning device comprising:
- an azimuth calculation section which calculates an azimuth of the SPS satellite corresponding to the received satellite signal; and
a reception environment determination section which determines a reception environment including a multipath environment based on the azimuths of the SPS satellites calculated by the azimuth calculation section.
