NANOSAT ADCS ADAPTATIONS FOR CONTROL OF LARGE DEPLOYABLE STRUCTURES IN CURRENT MISSIONS

This paper will address the recent Guidance, Navigation and Control experiences and adaptations NanoAvionics has made with their 6U and 12U buses in controlling very large deployables. One structure is the NASA ACS3 Solar Sail, and the others are the AERO and VISTA High Frequency E and H field interferometry antenna systems. These structures are several times larger than the buses controlling them and the paper will examine the modelling of the deployables, the ACS adaptations and systems hardware design changes to accommodate them to meet the mission objective of Orbit raising and lowering for the sail and Radio Interferometry for the AEROVISTA constellation. Both are planned to be launched in 2022.
