Abstract
An altimetry system for a satellite, including an altimeter transmitting and receiving signals on at least one first frequency band; a radiometer receiving signals on at least one second frequency band, the altimeter and the radiometer being connected to one and the same antenna; reception means common to the altimeter and to the radiometer, and capable of amplifying and filtering the signals received from the antenna on a frequency band including the first frequency band and the second frequency band; means for separating the signals on the first frequency band from the signals on the second frequency band; the signals on the first frequency band being exploited to estimate an altimetric distance of the satellite, and radiometric measurements being exploited in order to correct the estimate.
