iACS200 Attitude control system

Hyperion Technologies

＜Outlines＞
The iACS200 series attitude control systems are low power, fully integrated attitude control systems, aimed at small satellites with a 3U CubeSat form factor or similar.
The standard version of the iACS200 integrates three MTQ200 series magnetorquers and offers interfaces for six (external) sun-sensors, allowing for different pointing modes.
The iACS200 can be equipped with three of Hyperion Technologies’ RW210 series reaction control wheels offering up to 6.0 mN.m.s of angular momentum storage per axis.
The iACS200 features an internal fire-and-forget controller, which frees up the host processor’s workload, providing pointing and de-tumbling modes.
The iACS200 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 their CubeSat stack
