Sentinel-1A probe.

Copernicus, the European Earth observation program led by the European Commission in collaboration with the European Space Agency, announced the Satellite C and Satellite D of Sentinel-1, Sentinel-2 and Sentinel-3, that increases the fleet with two new probes for each program.

SENER has signed new contracts for these new satellites. This way, the company is going to supply instruments and mechanisms for the six new probes, replying the ones already developed for the Phase A and Phase B of these same missions. Therefore, for Sentinel-1C and Sentinel-1D is responsible for the deployment mechanisms for the four panels of the Synthetic Aperture Radar (SAR) antenna, which has nominally worked in orbit in Sentinel-1A and Sentinel-1B after its launch in April 2014 and 2016 respectively. For Sentinel-2C and Sentinel-2D, SENER will again develop the Shutter and Calibration Mechanism (SCM) for the Multi-Spectral Instrument (MSI) that allows this innovative and high-resolution multi-spectral satellite camera (with 13 bands) to be properly calibrated. A first mechanism with these characteristics is already operating in Sentinel-2A, launched in June 2015. Lastly, SENER will be engineering the selector mirror mechanism of a Flip Mirror Device (FMD) and its control electronics FMC (Flip Mirror Control) for the Sea and Land Surface Temperature Radiometer (SLSTR) of Sentinel-3C and Sentinel-3D. The first model of this mechanism was launched on February 2016 on board Sentinel-3A.

SENER’s participation in Copernicus also includes Sentinel-5, where the company is responsible for the optical bench of the UVNS SWIR sub-system (in ultraviolet and infrared ranges), which includes a high dimensional stability structure and the parts that screen and fix the optical elements.
