PURPOSE:To change easily a reference station by invalidating the reception processing which is based on a processing indication for the station allocating information given from the reference station in case two reference stations exist and then performing the reception processing to fetch the new station allocating information regardless of the processing indication of the station allocating information which is multiaddressed by the reference station when both a reference station and a spare reference station are decided. CONSTITUTION:The contact of a switch part 6 is turned to the side (b) by the output of a reference station information decision processing part 1 as long as both reference signal bursts can be received correctly with a reference station. Then a map processing indication applied from a terminal 10 is invalidated at an invalidity processing part 5 for map reception processing. At the same time, the contact of a switch part 7 is turned to the side (b). Thus the map processing indication is invalidated by the part 5 regardless of a map processing indication as long as the part 6 is kept at the side (b). Then the part 6 is turned to the side (a) with the output of the part 1 when the part 1 received correctly the information on either one of both reference stations. |
