Title:
SATELLITE POSITIONING SYSTEM, POSITIONING TERMINAL, POSITIONING METHOD, AND RECORDING MEDIUM
Document Type and Number:
WIPO Patent Application WO/2015/099194
Kind Code:
A1
Abstract:
A positioning terminal of a satellite positioning system receives a plurality of navigation signals and a reinforcement signal from a plurality of navigation satellites and a reinforcement satellite, respectively, and when positioning accuracy is enhanced through continuous observation, in a process for causing the values of error causes including ambiguity to converge through multiple observations, values for the terminal position of the positioning terminal that have been stored beforehand in a storage area are acquired, the value of each error cause is calculated, and positioning calculation is carried out successively while the error cause values are made to converge with each of the calculated values being used as an initial value and/or a single value to be added for continuous observation.
