This paper presents a novel architecture for implementing of Payload Control and Data Acquisition Sub System in the space missions. Monitoring and Data Acquisition from Different payloads in the satellites is one of important activities which plays vital role in maintaining of space missions. PCDAS collects all required data from other satellite sub systems and Prepare transmitting of the data to the ground station after data formatting according the existing standards such as CCSDS. The data synchronization and coordination with the on board computer of satellites and satellite’s communication sub system is very important for PCDAS. In this paper a new architecture for PCDAS is presented to act from satellite on board computer independently, so the satellite’s on board computer processing volume is reduced drastically. For presenting this novel architecture the new hardware configuration method that called dynamic partial reconfiguration is used. At the end of this paper proposed architecture is written in VHDL standard language and it is simulated and synthesized with ISE software. Finally proposed architecture implemented on the virtex-4 FPGA from Xilinx Company and desired results is presented.
