SSOC

Sun Sensor on a Chip

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

Analog Interface

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.

Digital Interface

Dos axis accurate sun sensor

SSoC-D device measures the incident angle of a sun ray in both axis. It includes a microprocessor that directly provides the sun light incident angles and their derivatives without external calculations, via RS-422 interface.

The high sensitivity is based on geometrical dimensions of the design. The use of a metal shield and a cover glass minimizes the ageing of the device under high radiation levels. Every sensor is calibrated and includes an internal thermistor.
