Title:
POSITIONING AUGMENTATION DEVICE, POSITIONING AUGMENTATION METHOD, AND POSITIONING AUGMENTATION PROGRAM
Document Type and Number:
WIPO Patent Application WO/2018/078795
Kind Code:
A1
Abstract:
In the present invention, a correction generation unit (110) generates correction amounts for the phase pseudoranges between a positioning satellite and a plurality of evaluation points as evaluation point correction amounts (111) for each of the plurality of evaluation points on the basis of the carrier wave phases of positioning signals (211a) observed at a plurality of electronic reference points. Further, a reference calculation unit (120) calculates the differences between the phase pseudoranges between the positioning satellite and the plurality of evaluation points and the geometric distances between the positioning satellite and the plurality of evaluation points as reference correction amounts (121) for the plurality of evaluation points. Additionally, a distance measurement error calculation unit (130) calculates distance measurement errors (131) for each of the plurality of evaluation points by removing a bias component resulting from ambiguity from the differences between the evaluation point correction amounts (111) and reference correction amounts (121).
