US Patent 9933508 Magnetic positioning management

Apparatus, method and computer program for magnetic positioning management. A management apparatus assigns an identifier for a transmitting mobile apparatus, and commands the transmitting mobile apparatus to transmit a radio beacon including the identifier. The management apparatus receives reception information from a receiving mobile apparatus that received the radio beacon, the reception information including the identifier of the transmitting mobile apparatus. For at least one of the transmitting mobile apparatus or the receiving mobile apparatus, the management apparatus determines its estimated location for a magnetic positioning based on an association of the transmitting mobile apparatus with the receiving mobile apparatus.
