Solar Azimuth Measurement and Orientation Sensor

SAMOS is an all mechanical SOLAR COMPASS module offered as an accessory for Instro’s Target Acquisition Systems.

The versatile solar compass module works in conjunction with Instro’s targeting application software to establish an accurate Azimuth Reference using alignment to the sun.

During the day the user follows a simple procedure to align the solar compass module to the sun using a process of shadow alignment. Once aligned, the targeting application software determines an accurate Azimuth Reference based on the sun position, time, date and own location.

Optimised for use by dismounted forces, the solar compass module is both lightweight and compact.

Proven principles and rugged construction have been employed to ensure long service life and reliability in the field.

The SAMOS solar compass module is a purely mechanical device requiring only the execution of simple procedures by the operator during deployment to provide an accurate azimuth heading relative to True North.
