Design of the Integration and Technical Verification and Validation Phase of the Ground Segment of the Hyperspectral Satellite Mission EnMAP

Kurzfassung

EnMAP (Environmental Mapping and Analysis Program) is a German hyperspectral satellite mission, with a ground segment operated by the Earth Observation Center (EOC) and the German Space Operation Center (GSOC) of the German Aerospace Center (DLR). The Ground Segment comprises all the facilities and systems required on Earth to control and operate the mission. It specifically facilitates access for the user segment to the space segment, including the commanding of the satellite, ordering and receiving data, and finally the processing, archiving and distribution of data. This paper gives an overview of the design of the Integration and Technical Verification and Validation (ITVV) phase of the Ground Segment. It starts with the design of the Ground Segment resulting in the development model, which consists of the requirements imposed on the Ground Segment, the spanning of the product tree with its contributing subsystems and their further differentiation, and the interfaces connecting them providing the needed functionality. This view of the Ground Segment is complemented with a model based on use cases allowing to characterize the Ground Segment by its dynamic behaviour fulfilling the above tasks. Based on the above knowledge the different stages of the ITVV Phase are presented and the dependencies between the phases are pointed out, to finally guarantee a fully validated mission.
