摘要： A system for surveying aircraft present in an area covered by at least one communication satellite, the aircraft transmitting signals conveying surveillance messages. The coverage area consists of multiple spots, the satellite is configured to periodically apply a switching sequence, the sequence consisting of multiple switching phases, a switching phase corresponding to a duration during which the signals transmitted by the aircraft present in at least one spot are processed by the satellite in such a way as to detect surveillance messages, and the sequence is adapted to allow for the detection, during a predetermined period Tup, of at least one surveillance message by aircraft present in the coverage area.

摘要： A technique for configuring, in real time, an equipment item receiving and processing primary signals which are transmitted to it by satellite link, the technique including transmitting secondary signals with frequencies spread over a band at least partially overlapping a frequency band occupied by the primary signals, the secondary signals including signalling parameters which are used, in real time, by the equipment item to configure processing applied to the primary signals. The technique is applicable to dynamic switching of beams in a multi-beam satellite and to dynamic switching of frames, for example in a time-division multiple access system.
