As part of the GMES system, Sentinel-1 is designed to provide an independent and operational information capacity to the European Union to warrant environment and security policies and to support sustainable economic growth. Sentinel-1 is a satellite system designed to operate a ground segment for 20 years supporting a system of up to three satellites. One satellite is built to perform at least seven years in the reference orbit and to operate a SAR instrument in C- band. Product quality is of paramount importance. Hence, the success or failure of the mission is essentially dependent on the calibration of the Sentinel-1 system ensuring the product quality and the correct in-orbit operation of the entire SAR system. The essential task of calibrating Sentinel-1 is to estimate and correct systematic error contributions throughout the complete SAR system and to tie-down image information (magnitude and phase) to reference units in geophysical terms. The quality of this calibration process is dependent on the inherent stability of the radar system and the capability to determine and monitor the radiometric and geometric characteristics. |
