SSALT
Single-frequency Solid State Radar Altimeter (SSALT, a.k.a. Poseidon-1) was an experimental instrument designed by CNES and intended to validate the accuracy, operation, and signal processing of a small-volume, lightweight, low-power altimeter. Poseidon-1 used the same antenna as the NASA altimeter and had similar operating principles and performance, but it only operated at a single frequency of 13.6 GHz. SSALT (Poseidon-1) was the predecessor of Poseidon-2, which is described in greater detail in the Jason entry.
