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.

Workshop on Vicarious Infrastructure for OCR (Ocean Colour Radiometry)

02 March 2017

The ESA workshop "Options for future European satellite OCR (Ocean Colour Radiometry) vicarious adjustment infrastructure for the Sentinel-3 OLCI and Sentinel-2 MSI series", organised by the FRM4SOC team (Fiducial Reference Measurements for Satellite Ocean Colour) was held at ESRIN, Frascati from 21 to 23 February 2017.

All presentations of the workshop and extended abstracts will be published at the workshop website. The proceedings of the workshop will be also published later this year, with expected contributions from international scientists active in the field. The FRM4SOC review, in collaboration with the EUMETSAT parallel study, will conclude with a set of requirements and justified recommendations (based on community consensus evidence).
