Attitude Determination & Control System

The iADCS400 is a fully autonomous attitude determination and control system aimed at small satellites with a 6U CubeSat form factor or larger

The iADCS400 was developed for platforms ranging 6-12U size. It matches the ST200 star tracker with our RW400 reaction wheels, the MTQ400 series of magnetorquers as well as optional control algorithms featuring various standard modes. It offers an entirely autonomous attitude control system, in the space of 5 standard CubeSat PCB’s, taking up 0.7U in terms of volume.

The iADCS400 features an internal fire-and-forget controller, which frees up the host processor’s workload, providing nadir and target-pointing modes, as well as backup de-tumbling, intentional spin modes and slewing for 6 to 12 U satellites or platforms with similar moments of inertia.

Modes

The iADCS400 features an internal fire-and-forget controller, which frees up the host processor’s workload, providing nadir and target pointing modes, as well as backup de-tumbling, intentional spin modes and slewing for 6 to 12 U satellites or platforms with similar moments of inertia.

Adaptability

The iADCS400 is delivered with a PC104- compatible footprint, consuming the space of 4 standard CubeSat PCB’s, or a total of 0.7 U. This allows the placement of the iADCS400 system anywhere in the CubeSat stack.

Design 

Designed for 6 – 12 U platforms the iADCS400 has low mass of 1150 to 1700 g, low power of <4 W peak, and outer dimensions of 95.4 x 95.9 x 67.3mm. The fully autonomous attitude determination and control system has additional radiation shielding built in, plug-and-play ready design and with three-axis magnetorquer configuration with up to 0.5 A.m² of magnetic dipole moment.
