The Horizon Sensor for Nano and Micro Satellites (HSNS) is a four-element thermopile sensor designed for Earth detection and Nadir vector determination, providing reliable attitude information for nano and microsatellite platforms.

Using four infrared sensing elements, the HSNS measures infrared radiation from the Earth and space to determine the Earth horizon and support accurate spacecraft attitude determination.

Built on extensive experience in spacecraft attitude sensing and infrared detection technologies, each HSNS unit is individually characterized and tested to ensure consistent performance.

An integrated microcontroller simplifies connection with the spacecraft ADCS, providing fast and straightforward system integration through digital interfaces including UART and I2C.

Combining compact design, infrared sensing and integrated processing, HSNS provides an effective attitude-sensing solution for nano and microsatellite missions.
