Positioning satellite signal receiver, the processing method of the positioning satellite signal receiver, and, the program

摘要

PROBLEM TO BE SOLVED: To provide a positioning satellite signal receiver, a positioning satellite signal receiver processing method, and a program capable of suppressing miscalculation of a motion velocity or the like when multipath waves only are received from a satellite.;SOLUTION: The positioning satellite signal receiver comprises at least a calculation part 106 for repeating velocity calculation processing to obtain a plurality of unknown directional velocity components and unknown clock drifts on the basis of received positioning satellite signals from a positioning satellite. The calculation part 106 determines whether a difference between a most recent clock drift obtained most recently and a past average of multiple clock drifts having been obtained exceeds a predetermined threshold. When the difference is determined to exceed the predetermined threshold, the calculation part 106 employs the past average of multiple clock drifts as a most recent clock drift and employs a plurality of directional velocity components obtained by velocity calculation processing for obtaining only a plurality of directional velocity components, as a plurality of most recently obtained directional velocity components.;COPYRIGHT: (C)2013,JPO&INPIT
