FSS100 - Nano Fine Sun Sensor

FSS100 - Nano Fine Sun Sensor image


Fine Sun Sensors measure the sun vector on satellite body reference frame using specially designed optical structures and electronics. Sun vector information should be fed into the attitude determination and control system (ADCS) to facilitate the attitude determination process. Fine Sun Sensors are comparatively accurate than magnetometers; Moreover, they are smaller, lighter, cheaper, consume less power, and update faster than star trackers or earth sensors.

FSS100 was designed and manufactured by Tensor Tech feature for their tiny size. Customers can easily install these devices on top of their CubeSat. Moreover, a microcontroller is embedded into FSS100 with an error table for a tabulated correction. Therefore, optimal performance could be extracted via in-factory calibration in Tensor Tech; or, users can calibrate these sensors by themselves using the supported software.

Please noted that fine sun sensors and coarse sun sensors could only work when the satellite is orbiting to locations where the sun is capturable; in addition, a sun model calculation is necessary for telling the attitude of a satellite. Details could be found in the FSS100 user manual or consulting with Tensor Tech's team.
