Abstract:	With greater role that GPSR possesses in the autonomy enhancement of navigation and the facilitation of operation for a variety of spacecrafts and rockets, many key players in the global space arena pour numerous resources into the development of the autonomous space-borne global positioning system receivers, including National Space Organization (hence NSPO) of Taiwan. Two missions considered during the development course of space-grade embedded software receiver (SESR) are FORMOSAT-7/COSMIC-2 and Sounding Rocket. To thoroughly validate the performance of the proposed SESR, a platform to emulate the attitude control and dynamics/environments software simulator (hence ACDESS) of these two missions in real time is required. In this paper, an ACDESS platform built on the PXI system manufactured by National Instruments is proposed. The platform consists of necessary interfaces to work with GPS RF signal emulator by injecting motion data to the controller of RF signal generator. The end-to-end accuracy of NSPO SESR for both scenarios is better than 8 meters (1?, 3D) which implies its promising perspectives for the two missions.
