The D-Sense from D-Orbit is a Multi-Sensor ADCS Module that can track the position of the sun, earth’s horizon, magnetic field and the angular rate of the spacecraft. It has an energy consumption of 300 mW in standard operating mode and 500 mW in camera mode. This sensor system supports the CAN bus interface and provides complete attitude determination coverage. It consists of photodiodes for sun sensing, thermopiles for earth horizon sensing, magnetometer for earth magnetic field sensing, gyroscope for angular rate sensing and a camera for photos, videos and star tracking. The system has a mass of less than 200 g and the module measures 70 x 70 x 55 mm. It is ideal for satellite constellations.
