The ASSET client interface: balancing high level specification with low level control

This paper describes an advanced client interface for spacecraft operations. This interface permits system clients to specify operations at a level of abstraction relevant to their experience, need, and desire. The interface encourages high-level specification of desired products in which only the relevant product attributes are described. This mode is simple, convenient, and promotes system level flexibility through the elimination of unnecessary constraints. More sophisticated clients may augment this process with lower level directions that mandate particular command and telemetry operations or constrain specific operational variables.
