CNES is providing a Ku- and C-band nadir altimeter almost exactly the same as the Poseidon-3 model carried on Jason-3. This instrument is designed to complete KaRIn to ensure nominal continuity of long-wavelength altimeter measurements (>1000 kms) and can also be used to calibrate the interferometric radar altimeter. This altimeter is expected to operate to the same level of performance as that of Poseidon-3.
