Positioning apparatus, positioning method, positioning program, and computer-readable recording medium for recording positioning program
First Claim
1. A positioning apparatus comprising:
- a satellite selection indicator information generating device being configured to generate satellite selection indicator information based on satellite location information of SPS (Satellite Positioning System) to select a plurality of said SPS used to position;
a positioning device being configured to acquire positioning information using said plurality of SPS selected based on said satellite selection indicator information;
an outputting device being configured to output said positioning information;
a reception environment indicator information generating device being configured to generate reception environment indicator information of said SPS configured to said satellite selection indicator information with respect to positioning precision and calculated based on reception environment information contained in electric waves from said SPS; and
a positioning information evaluation device being configured to determine whether said positioning information is output to said outputting device or not based on said satellite selection indicator information and said reception environment indicator information.

Abstract
A positioning apparatus 100 includes: a satellite selection indicator information generating device 121 that generates satellite selection indicator information based on satellite location information 131 of SPS to select SPS to be used for positioning; a positioning device 111 that acquires positioning information 135 using the SPS selected based on the satellite selection indicator information; and an outputting device 102 that outputs the positioning information. The positioning apparatus includes: a reception environment indicator information generating device 123 that generates reception environment indicator information 134 for the SPS to compare to the satellite selection indicator information with respect to positioning precision, and calculated based on reception environment information contained in electric waves from the SPS; and a positioning information evaluation device 120 that determines whether the positioning information is to be output to the outputting device or not.
