On April 25, 2024, the VERTECS project conducted a PDR (Preliminary Design Review). The purpose of the PDR was to verify the consistency between the system requirements and the subsystem design, and to provide feedback on the BBM tests conducted for each subsystem, etc. During the PDR, team members gave presentations on the satellite subsystem configuration, design, and test results. After the presentations, there was a question-and-answer session, and a lively discussion ensued.
