Summary
The Tensor Tech FSS100 - Nano Fine Sun Sensor is designed to provide a compact, low power sun sensing solution with a high update rate. The system senses the direction of sunlight in two vectors, with accurate pointing knowledge.
The FSS100 enables the accurate measurement of the sun vector on a satellite body reference frame, using specially-designed optical structures and electronics. This information is used by the Attitude Determination and Control System (ADCS) to facilitate attitude determination.
The FSS100 is east to integrate into a CubeSat and the system can also be operated as a coarse sun sensor if required. It has been designed to minimize suns sensing size and mass requirements.
A microcontroller is embedded, with an error table for a tabulated correction. This enables optimal performance to be extracted via in-factory calibration by Tensor Tech, or users can calibrate sensors by themselves using the supported software.
For less strict performance requirements, Tensor Tech also offers a coarse sun sensor: CSS100.
