Abstract: A steering correction signal generator module (MC) for generating steering correction signals (SC) for an automatic pilot for automatically steering a sailboat comprises: an inlet (EM) for a signal (SM) indicating movement of the sailboat that is caused by waves; a processing unit (UE) for generating a steering correction signal (SC) on the basis of the signal (SM) indicating movement of the sailboat; and an outlet (SSC) for the steering correction signal (SC); in which module the steering correction signal (SC) is determined in a manner such as to cause the course of the sailboat to be corrected towards the direction from which the waves are coming in correspondence with their crests (CI, CII) and away from the direction in correspondence with their troughs (CR). The invention also relates to an automatic pilot system for automatically steering a sailboat, which system includes such a module (MC).

Abstract: A procedure for control of a scanning antenna including:a central modulation-management unit (OBS) incorporating an external angular scanning and packet-synchronization bus (BRC),at least N modulation-control devices (MOD.sub.1, . . . MOD.sub.N),at least one beam-forming device (BFN),at least one network comprising M antenna elements (A.sub.1, . . . A.sub.M), the central management unit (OBS) incorporating N first terminals connected respectively to N second terminals of the beam-forming device (BFM) through the N modulation-control devices (MOD.sub.1, . . . MOD.sub.N), and the beam-forming device (BFN) incorporating, on the one hand, M third terminals connected respectively to the M antenna elements respectively (A.sub.1, . . . A.sub.N), and, on the other, a scanning and synchronization terminal connected to the external bus (BRC).
