Abstract
A method for generating a circular polarisation signal from at least two transponders of a satellite able to process linearly polarised signals includes: a transmission of at least two linearly polarised signal components so as to produce a circularly polarised signal by at least two transponders of a satellite; processing signals by the two transponders of the satellite to produce a circular polarisation of the signals transmitted by the satellite; ground receiving by at least one circularly polarised antenna; measuring a physical parameter from the received signals, and determining a correction parameter to be applied to the generation of the components of linearly polarised signals; generating a compensation of the components of linearly polarised signals transmitted to the satellite.
