Developing and upgrading the data processing algorithms in order to meet mission requirements and user needs.
Calibrating the sensors (through the update of on-board and on-ground configuration data) in order to meet product quality requirements.
Validating the generated products assessing, by independent means, the quality of the generated EO data products.
Routine Quality Control
Monitoring routinely the status of the spacecraft (payload and platform) and to check if the derived products meet the quality requirements along mission life-time.
The activities related to the SPPA constitute a long and continuous process involving a number of various actors with different competencies and objectives.
