測位装置
Document Type and Number:
Japanese Patent JP4091276
Kind Code:
B2
Abstract:
In order to solve a conventional problem that precision deterioration that cannot be determined by only a DOP, a positioning system is provided which comprises: a receiver for receiving signals from a plurality of positioning satellites to output data received from satellites; a satellite selector for selecting a plurality of combinations of positioning satellites to be objects of positioning calculation based on the data received from satellites to output satellite combination data; a positioning calculator for performing positioning calculation based on the data received from satellites and the satellite combination data to output positioning results thereof; a velocity detector for detecting a velocity of the positioning system to output velocity data; and a positioning output determining unit for selecting a positioning result closest to a predicted position out of the positioning results to output the positioning result as a positioning output.
