Narrative:
We exited the base through the RAM airlock and walked slowly uphill to the concrete patch, with the last bar and the tools needed. We also took the drone with us and took some images and videos of the Corner Reflector installation. We proceeded to the CR and installed the last of the bars. Then, we moved the antenna to its final configuration, using the three mounted bars that hold the stick with the antenna on top. We attached the stick to the bars and levelled the antenna and stick. After some adjustments, the installation worked perfectly. Finally we fixed the coaxial cable to the ground with pegs.
With this EVA we have completed the Corner Reflector installation. We are correctly receiving data fro the GNSS antenna, and the first satellite pass from Sentinel-3B will be on the 14th of February at 17:51:40 UTC and Sentinel-3A on the 17Feb at 04:56:16 UTC.
