PEARL (Propagation Experiment using kurz-Above-band Radio in Low earth orbit) CubeSat

Meeting & Discussion

PEARL (Propagation Experiment using kurz-Above-band Radio in Low earth orbit) CubeSat: PEARL is a 6U CubeSat with a Ku/Ka-band Communication Payload (KCP) to provide a high throughput satellite communication network and a Compact Ionospheric Probe (CIP) to monitor connection quality of global satellite communications and outage of navigation signals. KCP with software defined radio built by National Central University (NCU)/Industrial Technology Research Institute (ITRI) provides domestic companies a high throughput satellite communication network with transponder mode, communication mode, and channel sounding mode for verification and test on satellite communication ground equipment.

Under time and budget constraints, a 6U CubeSat was proposed for domestic satellite communication industry and space science development. To reduce high power requirements of the regular Ku/Ka-band communication payload, A high accurate attitude determination and control subsystem is used to direct a high gain horn antenna precisely to ground stations instead of high power requirements of a steerable phased array antenna.

Taiwan started Beyond 5G LEO communication satellite project in 2021 to encourage domestic companies to develop satellite communication ground equipment to meet the demands from major LEO communication players (like SpaceX, OneWeb, Telesat, Amazon, etc.). An experimental 6U CubeSat with a high throughput Ku/Ka-band communication payload and a CIP was proposed to launch at the end of year 2022 as a pathfinder and early test platform of the upcoming Beyond 5G LEO communication satellite for companies (like Pyras Tech. Inc., Rapidtek Tech. Inc., Foxconn Interconnect Tech. Ltd., 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.
