K/Ka-Band Communication Payload for Low Earth Orbit CubeSat

Meeting & Discussion

The purpose of this project is building a multi-function communication experimental payload for a CubeSat named PEARL (Propagation Experiment using kurz-Above-band Radio in Low earth orbit). The payload comprises Software-Defined Radio (SDR) Platform, K/Ka-Band RF frontend and antennas.

The main technique breakthrough of this project is on the building of a multi-function communication experimental payload for the PEARL CubeSat. The payload comprises Software-Defined Radio (SDR) Platform, K/Ka-Band RF frontend and antennas. The function of the complete LEO CubeSat communication payload is configurable which is designed and implemented on the FPGA part of the SDR platform. The modes of the communication system for LEO CubeSat include: 1) Transponder Mode; 2) Transceiver Mode; 3) Payload Communication Mode; 4) Channel Sounding Mode.

Recently, the techniques using LEO satellite constellation for providing high-throughput mobile communications with wide coverage are attracting many academic/industrial research/development interests, such as SpaceX, OneWeb, Telesat, Amazon. The main goal of this project is on the building of a multi-function communication experimental payload for the PEARL CubeSat, which is capable of a chance for setting up the required core techniques domestically and also providing a real-field experimental environment for related domestic industries such as antenna, RF, modem and etc..

National Central University

National Central University is a public research university with long-standing traditions of the Republic of China based in Taiwan. It was founded in 1902 and renamed in 1915. The school was initially located in Miaoli when it first moved to Taiwan, but relocated to Zhongli in 1962 and developed into a comprehensive university. It's the first university in Taiwan to research industrial economics,[3] and economic development (Taiwan's Consumer Confidence Index is released monthly by NCU).[4] NCU is a member of AACSB.[5] NCU is one of the six national universities in research selected by the Ministry of Education.
