Abstract: A method and installation for calibrating an airborne goniometry apparatus by means of a calibration generator, remote from the airborne goniometry apparatus. The method includes sharing, between the goniometry apparatus and the calibration generator, a calibration sequence. The method also includes sharing, between the goniometry apparatus and the calibration generator, a start time of the calibration sequence. The method further includes executing the calibration sequence by the goniometry apparatus and by the calibration generator, at the start time. The start time is determined in reference to the same clock, referred to as a reference clock, provided to the goniometry apparatus and the calibration generator, by an external source.

Abstract: A method for aggregating and regulating messages in a network that has a plurality of pairs of nodes and two transmitting/receiving devices communicating via a bidirectional channel. The method is implemented by each of the transmitting/receiving devices. Each received message may be segmented into packets of a predefined size, and each packet may be allocated to a queue that depends on the origin, the destination, and the priority of the message. One or more frames may then be created, and packets of the queues may be inserted into the frames. Frames may then be sent via the bidirectional channel over a predefined time interval, the number of frames sent over the time interval being dependent on the maximum throughput of the channel and on the useful throughput in each of the transport directions of the channel.
