Mobile positioning system, a central station and a question control method and a program for use therewith

摘要

mobile measurement system, receives a response signal from the mobile (aircraft 5) a plurality of receiving stations (1-1 through 1-4) which is constituted from a central station measures the position of the moving object based on the reception time of the response signal in a plurality of receiving stations (3), the central office Te measuring the geometric position of the mobile object from the reception times of a plurality of receiving stations. Mobile location measuring system includes at least one or more transmission devices for transmitting an interrogation signal to obtain a response signal to the mobile (transceiver station 2), the interrogation signal to the central station (3), the transmitting apparatus transmits and Yu and interrogation signal determining means for determining a transmission time, a generating means for generating an interrogation signal and transmission times which is determined as the question control information, and means for sending a query control information generated by the generation means to the transmitter are doing. This provides a reliable and secure and capable of increasing mobile position measurement system of multilateration system.
