<P>PROBLEM TO BE SOLVED: To keep the number of mode S addresses for holding in a mode S address table to be an irreducible minimum and also to keep the addresses to be the latest state by utilizing a transmission period of an acquisition squitter or an extended squitter transmitted from an aircraft transponder. <P>SOLUTION: The mode S addresses are extracted by an All Call Error Correction 2 and accumulated in a mode S address table 5. The accumulated mode S addresses are deleted by a Timer Reset Cntrl 6 for every delete period longer than the transmission period of the acquisition squitter or the extended squitter. The mode S address and data are extracted by a Roll Call Error Correction 8 from an individual identification response 9 transmitted from the aircraft loading transponder. The mode S addresses contained in the individual identification response and all mode S addresses accumulated in the mode S address table 5 are compared and collated by a Comp CNTRL 7 to correct error. <P>COPYRIGHT: (C)2012,JPO&INPIT |
