    Fine (Digital) Sun Sensor

    The front surface of the sensor is a synthetic sapphire window with a reflective metal coating beneath. Slits are etched in the metal and sunlight passes through them and through an optical filter onto a sensor. The charge on the photo-sensors are read by the microcontroller which processes the image and computes the sun vector. The vector and other telemetry is returned to the spacecraft through the serial interface.

    The NewSpace Fine Sun Sensor accecpts configuration commands and outputs digital angles and telemetry over a serial interface on the on-board computer. The unit can be powered from unregulated DC power from the spacecraft.
