Price on request

A CubeSat Attitude Control System (ACS) measures orbit position, absolute attitude, spacecraft rates and can also control the orientation of the satellite through either magnetic actuation or wheel based solutions. The NewSpace ACS board is a single PC104 board (15mm height) that physically integrates three high accuracy sun sensors, a magnetometer, MEMS gyros, a stellar gyro and two magnetorquer rods. Additionally, external interfaces allow for a further three sun sensors, the Z-axis magnetorquer as well as momentum or reaction wheels.
