SISTEMAS DESSoC - A60 SOLAR ILUMINACIÓN 2 AX IS ACCUR ATE SUN SENSOR SSoC-A is a miniaturized analog sensor for the sun position determination Sun Sensor on a Chip (SSoC), is based on MEMS fabrication processes to achieve highly integrated sensing structures at low cost for high accurate sun-tracking and positioning systems. SSoC-A device measures the incident angle of a sun ray in both axis. The high sensitivity is based on geometrical dimensions of the design. Every sensor is characterized and a look-up table is provided for its application. It includes an internal thermistor for temperature compensation. The use of a metal shield and a cover glass in the objective minimizes the ageing of the device under high radiation levels. SECCIÓN LONGITUDINAL Satellite attitude determination.
