SSoC-D60 Satellite Sun Sensor


The Sun Sensor on a Chip (SSOC) architecture, achieved through a MEMS fabrication process, results in a highly integrated sensing structure, providing accurate and reliable sun-tracking, pointing and attitude determination. The SSOC-D60 device measures the incident angle of the sun’s rays in two orthogonal axes, leveraging the geometrical dimensions of the design to provide high sensitivity in a form factor perfect for small satellites.

Unlike its analog counterpart, the digital SSOC-D60 includes an internal microprocessor that calculates and outputs the sun light incident angles and their derivatives without external computation. Available digital interface options include UART, I2C, SPI or RS-422. Every sensor is calibrated, characterized and includes a metal shield and cover glass over the optical eye to minimize ageing in higher radiation environments.
