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

Application of an Algorithm Change Process to the GOES-R Ground Segment Ryan Williams, Stellar Solutions/GOES-R Ground Segment Product Readiness and Operations

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 poster will describe the algorithm change process as implemented on GOES-R, and the benefits to the program resulting from the algorithm change process. The roles and responsibilities of the process as the program evolves from the pre-launch phase, to the post-launch product testing, into operations and through handover of the ground segment form the GOES-R program to OSPO will be described.
