Algorithm Development

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.
