Summary

The Solar MEMS HSNS is a Horizon Sensor designed for nanosatellites.

It is a Quad Thermopile sensor for Earth detection and Nadir vector determination. This device measures the infrared radiation from Space and from Earth with 4 IR-eyes, providing accurate and reliable detection and attitude determination.

The HSNS is based on previous experience with Solar MEMS making attitude sensors and long research projects on IR sensing devices. Every HSNS is characterized and tested and includes a microcontroller for fast integration with different options like UART or I2C protocols.
