碩士 === 國立中央大學 === 太空科學研究所 === 103 === Advanced Ionosphere Probe (AIP), a science payload aboard the FORMORSAT-5 satellite, is combined with a sensor head and a control unit, Science Payload Electronics Unit (SPEU). The SPEU is used to control AIP operation and to communicate with Command and Data Management Unit (CDMU). Under the current configuration, the AIP is difficult to be installed inside a CubeSat or a MicroSat due to volume and mass. In this thesis, a Digital Control Unit (DCU) is developed to replace the SPEU and can be installed inside the AIP sensor head compatibly. The new configuration simplifies communication difficulties and results in extremely reduction in the physical property but the same capabilities. The DCU uses Xilinx Spartan-6 Field Programmable Gate Array (FPGA) and is programmed in VerilogHDL. The schematic of the DCU is designed by NI Multism and the layout finished by NI Ultiboard under standard designs of the Xilinx Spartan-6 FPGA. All the DCU functions have been verified by an in-house Electrical Ground Segment Equipment which is constructed by NI CompatctRIO with in-house modules and programmed in NI LabVIEW.
