SUN SENSOR on a CHIP Technology

Two accuracy axes. Field of view of ±60º. Accuracy better than 0.3º (3σ error). Interface of 4 analog signals. Dimensions about 30x30x12 mm. Useful in space and aeronautics. Engineering model available.

Sun Sensor on a Chip (SSoC), is based on MEMS fabrication processes to achieve highly integrated sensing structures for high accurate sun-tracking, positioning systems and attitude determination.SSOC-A60 device measures the incident angle of a sun ray in two axes. The high sensitivity is based on geometrical dimensions of the design.Every sensor is calibrated and characterized, and a look-up table is provided for its application. The use of a metal shield and a cover glass in the optical eye minimizes the ageing of the device under high radiation levels.
