Relying on its many-year experience of optoelectronic instrument development and optomechanical systems integration, ITRC is now in its eighth year of participating in the FORMOSAT-5 remote sensing payload development project. ITRC's primary goal is to develop and produce a remote-sensing imager for the satellite's remote-sensing payload, and assist with integrated test of the payload. As the launch of the FORMOSAT-5 draws near and considers the increasing needs for satellite images featuring enhanced resolution, ITRC proposes to conduct a preliminary research on second-generation payload system (three-mirror anastigmat, TMA). Remote sensing payload is Taiwan’s first self-reliant satellite payload integrated into the FORMOSAT-5. Remote sensing payload is jointly developed by NSPO and ITRC, through the process of specification establishment, system design, component assembly, and integration test. Specifically, the Electronic Unit (EU) was provided by the National Chung-Shan Institute of Science and Technology, the focal plane by CMOS Sensor Inc., the solid-state memory by Camel, and mechanical elements by Aerospace Industrial Development Corporation. Our payload is the combined efforts exerted by major groups in Taiwan. This year, ITRC has accomplishedits assistance in the test of remote sensing payload and delivered the payload for subsequent satellite integration.
