Abstract
The ONGLAISAT CubeSat, jointly developed by Taiwan Space Agency (TASA), the University of Tokyo, and Ark Edge Space, was launched in Q4 2024 to conduct optical remote sensing. To support downlink operations via S-band, National Central University (NCU) established a backup ground station. A complete lifecycle plan was implemented, incorporating Software Defined Radio (SDR)-based signal analysis, CCSDS-compatible telemetry visualization via WINGS, and end-to-end RF testing. Initial on-orbit signals were successfully received in Q1 2025. Doppler shift and power fluctuation analysis demonstrated system performance and operational readiness. In addition, signal comparison can serve as an alternative method for determining the satellite's orbit and attitude. This work highlights the role of SDR in enhancing ground station flexibility and reinforces the value of international collaboration in small satellite missions.
