MetOp-SG-B Weather Satellite: Scatterometer Flies Through Tests

Date: Issue 113 - April 2022

The flight model of the Scatterometer Antenna Subsystem (SAS) of the MetOp Second Generation meteorological satellites has been officially delivered after four months of extensive testing at the Airbus facility in Madrid. It will now be transferred to Airbus in Friedrichshafen (Germany) where it will be integrated into the satellite along with the other instruments.

The SAS protoflight model underwent a lengthy test campaign where it was subjected to the extreme conditions that it will encounter during launch and in-orbit operation. These tests included: antenna deployment, thermal cycling, mechanical vibrations, and acoustic environment.
