Title: LOCAL ERROR GENERATION DEVICE, LOCAL ERROR GENERATION PROGRAM AND POSITIONING REINFORCEMENT INFORMATION DISTRIBUTION SYSTEM
Abstract:
In this local error generation device (500), a local error estimation unit (515) estimates and generates a local error (δT, δI) on the basis of a global error (δo, δt, δb) included in positioning reinforcement information (81) compiled in an electronic reference point network (120) and observation data (61) generated by a receiver at the electronic reference point (611, 612) which does not belong to the electronic reference point network (120). The local error (δT, δI) is an error which influences positioning accuracy in an area in which the electronic reference point (611, 612) exists and depends on the area in which the electronic reference point (611, 612) exists.
