A Guidance, Navigation and Control (GN&C) Implementation of Plug-and-Play for Responsive Spacecraft

Abstract:

It is becoming more important to the space community that spacecraft be developed in direct support of responsive missions, which implies that spacecraft need to be “built to inventory”, constructed from off-the-shelf components based on varying mission needs, and/or integrated rapidly with payloads as they are identified and available. Microcosm, in conjunction with HRP Systems, under several SBIRs from AFRL/VSSE, has developed a rapid prototype implementation of Plug-and-Play (PnP) components and generic core algorithms that are focused on a guidance, navigation, and control (GN&C) application for spacecraft scheduled for demonstration on the AFRL PnPSat. This paper will address architectural issues that drive a PnP implementation of the GN&C function, with an emphasis on identifying and understanding all of the pros and cons associated with this implementation path. Additionally, the paper will examine the Microcosm/HRP Systems approach to GN&C design, including software partitioning, algorithm development, and performance testing.
