AbstractIt is difficult to transmit directly the data circulating on a 1553-B bus by microwave link during a missile test, given that it is not a synchronous message. For the ANS missile the AEROSPATIALE tactical missile division has decided to include the 1553 message in a PCM message to IRIG standards. In view of the asynchronism between the traditional telemetering data and the bus message it has been necessary to develop a specific controller providing the interface between the bus and the IRIG PCM. This controller performs the functions of synchronization, encoding, structural analysis of message, adaptatin of the input speed to the PCM rate and also dating of the data. Moreover, during tests on the missile, it is necessary to process the bus data on the ground. A conventional decommutator, although suitable for the usual analog channels, cannot be used in real time. It is therefore been necessary to develop equipment providing on the ground the reconstitution of a 1553 bus that can be processed by ordinary standard equipment. After synchronizing and sorting the data in the IRIG format the equipment creates three types of messages corresponding: to the missile message, to the dating and to the message found erroneous during acquisition on board.
