Research Institution

The primary objective of the Phase I investigation is to develop and demonstrate an innovative solution that can enable very high precision pointing accuracy (<0.08 degree nominal; <0.03 degree extended goal) at fast slew rates; providing part of a advanced Smallsat/CubeSat precision attitude determination and control system (PADCS) that can meet emerging very stringent missions requirements. The Phase I program aim is to design and fabricate initial prototype hardware, including power electronics and Reaction Wheel Assembly (RWA) modifications as to demonstrating such positional accuracy capability, power cost (peak and average power consumption), slew rates and mass/volume cost of the new solution. A critical objective of Phase I will be to develop at the decoupled control architecture for the new multi-stage Attitude Control System ACS controller that will be modeled, simulated, and then converted to hardware prototype for Phase I assessments. This goal is to integrate this prototype controller into a multi-stage (ACS) design hardware emulation testbed and evaluate actual performance before conclusion of the program.
