After antenna deployment, the test of RIME in the Near Earth Commissioning Phase are continuing successfully. With the 16 meters antenna completely deployed the sensitivity increased by 1000 times (or 30 dB) with respect to sensitivity before the deployment. The detailed test on the receiving chain of RIME show that the instrument is behaving as expected reaching its nominal performance.
