    • Descriptions

    The mission of SOC-i (Satellite for Optimal Control and Imaging) is to establish accurate orientations of the spacecraft by a GNC control system in order to reorient itself towards sun for recharging and towards the Earth for images. My team, Command and Data Handling (CDH) is dedicated to provide a system of operation with an onboard ARM-based MCU using Real-Time Operating System (RTOS). Our objectives include running a series of unmaned operations, establishing stable low-speed communications such as UART/I2C/SPI with other subsystems, healthchecking other subsystems by proactively pinging, and recovering from system failures.
