iADCS100 Attitude Determination And Control System

The iADCS100 is a fully autonomous Attitude Determination and Control System, aimed at small satellites with a 3U-CubeSat form factor or similar. It is a joint development of Hyperion Technologies B.V. and Berlin Space Technologies GmbH. The iADCS100 is based on the ST200 star tracker, complemented with RW210 series reaction wheels, and MTQ200 series magnetorquers.

The iADCS100 features an internal fire-and-forget controller, which frees up the host processor’s workload, providing nadir, sun and target-pointing modes, as well as backup de-tumbling and intentional spin modes.

The iADCS100 is delivered with a PC104-compatible footprint, consuming the space of 2 standard CubeSat PCB’s, or a total of 0.3 U. The CubeSat connector is fed through, allowing designers to place this system anywhere in the CubeSat stack.
