The U. S. Naval Research Laboratory (NRL) and The Johns Hopkins University/Applied Physics Laboratory (JHU/APL) are collaborating with the Integrated System Engineering Team (ISET) industry partners, to generate Bus Standards for Operationally Responsive Space (ORS) spacecraft. Bus Standards development is part of Phase III of the multi-phase ORS development effort initiated by the Office of the Secretary of Defense’s (OSD) Office of Force Transformation (OFT). The final development phase, Phase IV, is led by the newly formed ORS Office, leveraging these standards and other on-going efforts as inputs to the procurement of spacecraft buses for ORS systems. The ISET produced Bus Standards is examined and evaluated through prototype implementation. This paper provides details of the implementation of the Guidance, Navigation and Control (GNC) standards on the prototype spacecraft bus. The TacSat-4 mission, which will be placed in a highly elliptical orbit (HEO), uses this prototype bus along with the COMMx payload. In addition to applying the Attitude Determination and Control System (ADCS) bus standards to the TacSat-4 mission, this development effort is designed to provide feedback for updating the ORS bus standards generated by the ISET. Details of the GNC/ADCS bus standards as well as the outcome of their implementation on the TacSat-4 mission are provided.
