Abstract:
1. An altimetry system comprising: an altimeter transmitting and receiving signals on at least one first frequency band; a radiometer receiving signals on at least one second frequency band; an antenna connected to the altimeter and the radiometer; 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 comprising the first frequency band and the second frequency band; separation means for separating the signals on the first frequency band from the signals on the second frequency band; and a digital processing unit configured to exploit the signals on the first frequency band to generate an estimate of an altimetric distance of the satellite, and configured to exploit radiometric measurements of the second frequency band to correct the estimate, wherein the altimeter, the radiometer, the antenna, the reception means and the separation means are installed on board a satellite.
