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.

Landsat 8 Thermal Infra-Red Scanner (TIRS) Anomaly

13 June 2017

Image quality issues have been detected on the ESA Landsat 8 TIRS products which systematically contaminate the Band 10 and Band 11 TIRS data, the OLI data remains unaffected. Discussions are ongoing with the view to reprocess the Landsat 8 data with the latest software and supporting data to recover the affected products. More information can be found at the Landsat 8 Product Anomalies webpage
