PEARL (Propagation Experiment using kurz-Above-band radio in Low earth orbit) -1A and PEARL-1B CubeSats are integrated by National Central University (NCU) for educational training and scientific research. Each CubeSat is equipped with three payloads: an Inter-Satellite Link (ISL) payload, a Compact Ionospheric Probe (CIP), and a Perovskite Solar Cell (PSC) payload. The CIP is an all-in-one in-situ ion sensor developed by NCU to measure global ionospheric ion concentration, velocity, and temperature. It is installed on the CubeSat’s flight direction to monitor ionospheric space weather conditions and detect potential disruptions in space communication and navigation systems. The CIP is a mature payload that has been used on IDEASat (2021), INSPIRESat-1 (2022), ARCADE (2023), and PEARL-1C (2023). PEARL-1A and PEARL-1B are the next mission focusing on space weather, planned to deploy one after another in the same launch and are scheduled for Q1 2026.
