The Sensor Performance, Products and Algorithms (SPPA) is the element of the ESA Earth Observation ground segment responsible and performing the following activities:
Courtesy of Alfred Wegener Institute
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.

The Proba-V full-mission re-processing campaign has been completed,
On-line access for the current Collection (C0) will be discontinued by end February 2017.
The new Collection 1 (C1) data set includes significant quality improvements with respect to the previous data version Collection 0 (C0):
- Updated Cloud detection
- Re-fined radiometric calibration parameters
- Release of the intermediate L2a products
- Meta data compliancy to Climate and Forecasting conventions (v1.6)

The re-processing campaign of Proba-V Collection 1 products is proceeding, adopting the latest processor. Data from October 2013 up to September 2015 are now available to the user community. The re-processing campaign is expected to be finished by January/February 2017. Since 5 December 2016, the new processor was adopted for the near-real time processing.
