Among the Sener projects for 1- and 2-body deployment mechanisms, projects such as Sentinel 1 SAR antenna panel deployment stand out.
The Sentinel 1 satellite has a C-band Synthetic Aperture Radar (SAR). Thanks to this SAR instrument, Sentinel 1 will be able to provide high- and medium resolution data for the observation of land and coastal areas in cloudy areas and at night. It also has a radar with interferometric capabilities for detecting small land movements (at millimetric or sub-millimetric levels.
Sener performs the deployment of the Sentinel 1 SAR antenna, which has five panels (A, B, C, D and E). Of these, the central panel (C) is rigidly fixed to the top of the satellite and the other four (A, B, D and E) will be deployed in relation to panel C in a controlled sequence after the launch. They will then remain locked in the deployed configuration. The four rotating axes are parallel.
