The present invention relates to a frequency- and phase-modulation telecontrol receiver for a geostationary satellite which is lighter and less expensive than the contemporary receivers, while not degrading the bandwidth of the telecommunication equipment in respect of its useful load, and it is characterized in that it comprises a heterodyne amplifying and filtering analogue input circuit (28) followed by a digital processing circuit (49) configurable as an FM demodulation device or as a PM demodulation device, the analogue input circuit being common to both modes of demodulation.
La présente invention a pour objet un récepteur de télécommande en modulation de fréquence et de phase pour un satellite géostationnaire qui est plus léger et moins onéreux que les récepteurs habituels, tout en ne dégradant pas la bande passante des équipements de télécommunication de sa charge utile, et il est caractérisé en ce qu'il comprend un circuit d'entrée analogique amplificateur hétérodyne et de filtrage (28) suivi d'un circuit de traitement numérique (49) configurable en dispositif de démodulation FM ou en dispositif de démodulation PM, le circuit d'entrée analogique étant commun aux deux modes de démodulation.
