LOCAL ERROR GENERATION DEVICE, LOCAL ERROR GENERATION PROGRAM AND POSITIONING REINFORCEMENT INFORMATION DISTRIBUTION SYSTEM

摘要

A local error estimation unit (515) of a local error generation device (500) estimates and generates local errors (δT, δI) based on global errors (δo, δt, δb) included in positioning augmentation information (81) produced in an electronic reference point network (120) and observed data (61) generated by receivers on electronic reference points (611, 612) not belonging to the electronic reference point network (120). The local errors (δT, δI) are errors that influence positioning accuracy in a region where the electronic reference points (611, 612) exist and that depend on the region where the electronic reference points (611, 612) exist.
