Crystalspace AD1U Attitude Control and Determination System

Note: This specification is preliminary

Overview

Crystalspace AD1U attitude determination and control system is the smallest and the most advanced system in the market. It suits well for densely packed 1, 2 and 3 unit CubeSats. System is able to determine satellite attitude with accuracy of 0.1 deg and control attitude with accuracy of 1 deg. Wide variety of algorithms are available out of box. Furthermore, product comes with Crystalspace PC control software to help with system setup and calibration. Each sold unit has gone through acceptance testing.
