Title: POSITIONING AUGMENTATION DEVICE, POSITIONING AUGMENTATION SYSTEM, AND POSITIONING AUGMENTATION METHOD
Abstract:
In this positioning augmentation device (40), a planning unit (84) selects a subset satisfying selection conditions from a candidate set that is a set of satellites that are selection candidates and stores plan data (43) indicating the selected subset in a memory (72). A plan correction unit (85) acquires integrity information indicating the quality of the positioning signals transmitted from the satellites and detects a satellite having a positioning signal quality not meeting a quality requirement from the subset selected by the planning unit (84). In the subset, the planning correction unit (85) replaces the detected satellite with another satellite included in the candidate set. A message generation unit (87) makes satellites that are included in the candidate set and are included in the subset indicated by the plan data (43) stored in the memory (72) satellites for positioning augmentation and generates a message (41) for delivering augmentation information to be used for the positioning augmentation.
