Application of an Algorithm Change Process to the GOES-R Ground Segment

The GOES-R Ground Segment has instituted a formal algorithm change process. The formal process was needed to ensure that the many organizations involved in the calibration/validation activities are kept informed of the status of algorithms they are and/or are not expecting. The main focus of the algorithm change process is communication. It organizes scientific contributions prior to entering the software change process used by the Ground Segment Contractor. The algorithm change process also provides a mechanism for the scientist to verify the correctness of a change prior to implementation in the operational system by analyzing data from full system testing.

This talk will discuss how the GOES-R algorithm change process has evolved to stay agile with an operational satellite. In addition, improvements that have been made to allow for the implementation of new algorithms.
