SSOC-D60 2-Axis digital sun sensor
€13,890
The Solar MEMS Sun Sensor on a Chip (SSoC) solution is based on MEMS fabrication processes to achieve highly integrated sensing structures for high accurate sun-tracking, positioning systems and attitude determination.
The SSOC-D60 device measures the incident angle of a sun ray on both axis. It includes a microprocessor that directly provides the sunlight incident angles and their derivatives without external calculations, via a digital interface. The device includes MEMS technology with flight heritage, electronic components that are space-grade, and a microprocessor included has been tested for the space environment and has flight heritage.
The high sensitivity is based on the 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 characterized.
SSOC-D60 has flight heritage since 2009, with hundreds of flight models delivered for different missions.
