NRA

NRA or Nasa Radar Altimeter (206 kg including redundancy, 237 W), operating at 13.6 GHz (Ku band) and 5.3 GHz (C band) simultaneously is provided by Nasa. It is the fifth generation of altimeter; its design is based on the previous SEASAT and GEOSAT altimeters with significant improvements including the 5.3 GHz channel for the ionospheric measurement. It is the primary sensor for the Topex/Poseidon mission. The measurements made at the two frequencies are combined to obtain the altimeter height of the satellite above the sea (satellite range), the wind speed modulus, the significant wave height and the ionospheric correction.
