Independent Calibration of the Sentinel-1C SAR System

ASCII Citation
Klenk, Patrick und Giez, Jakob und Schmidt, Kersten und Nannini, Matteo und Schwerdt, Marco (2024) Independent Calibration of the Sentinel-1C SAR System. European Conference on Synthetic Aperture Radar (EUSAR), 2024-04-23 - 2024-04-26, Munich, Germany. (eingereichter Beitrag)

Kurzfassung
Sentinel-1C will be the third satellite of the Sentinel-1 mission. To be launched in early 2024, it will ensure seamless continuity of C-band SAR data for global monitoring of the Earth surface in the framework of the COPERNICUS program. In parallel to the commissioning of Sentinel-1C by the European Space Agency (ESA), an independent verification of the system calibration will be performed by DLR under an ESA contract. Based on an efficient calibration strategy, this paper describes the different activities to be performed by DLR and may present initial results obtained during the commissioning phase (CP) of Sentinel-1C.

This is from October 16, 2023, I didn't see it, was hidden at the bottom.
The report on the Zefiro-40 test failure was published on October 2.
So it should be known that the Vega-C will not be ready in Q1 2024.
Conclusion, there is already a launch order with "the other provider"?  ???

ESA director of space transportation Toni Tolker-Nielsen has announced that Vega C will return to flight on 15 November 2024. The agency is, however, considering Falcon 9 as a backup for the launch of Sentinel 1C.
