Digital Sun Sensor for SmallSats
The SSoC-D60 Satellite Sun Sensor with digital interface, is a low-cost navigational instrument used by spacecraft to detect and track the position of the sun for high accuracy pointing and attitude determination.
This reliable ITAR free solution is the perfect ADCS solution for nanosatellite, not only is it accurate but it is compact, lightweight and requires low power consumption.
More than 50 flight models of this 2-axis digital output sun-tracking sensor for SmallSats have been delivered to support over 15 missions.
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.
This solution features Sun Sensor on a Chip (SSOC) architecture, achieved through a MEMS fabrication process, a design which enables a highly integrated sensing structure, providing accurate and reliable sun-tracking, pointing and attitude determination.
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.
Reliable
The unit includes MEMS technology from Solar MEMS and the space-grade electronic components have significant flight heritage. This reliable ITAR free solution is the perfect ADCS solution for nanosatellites becasue, not only is it accurate, but also compact, lightweight and requires low power consumption.
Accurate
