Local error generation device, computer readable medium, and positioning augmentation information distribution system

A positioning augmentation information distribution system comprising:

• a transmission device to transmit positioning augmentation information for positioning, the positioning augmentation information generated by a network configured for a first region;
• and
• a local error generation device to:
• receive the positioning augmentation information;
• estimate and generate local errors that influence positioning accuracy in a second region remote from the first region, based on global errors included in the positioning augmentation information, the global errors being caused by satellites to transmit the positioning signals, and on observed data generated based on positioning signals received by a receiver that does not belong to the network and is installed at an electronic reference point located in the second region, the local errors depending on the second region and being caused by propagation paths of the positioning signals;
• and
• transmit the local errors to the transmission device,
• wherein the transmission device transmits new positioning augmentation information including the local errors transmitted from the local error generation device.
