MTQ800 Magnetorquers
Precise performance at high efficiency. The MTQ800 magnetorquers are aimed at applications in 50-200 kg class satellites.
Offering one of the highest energy efficiencies in the industry, combined with fine-grained dipole-moment strength control, it allows precise pointing and rapid de-saturation of any reaction wheels in the satellite.
With a unique boost-mode, these magnetorquers can be pushed up to higher magnetic dipole moments for short duration manoeuvres, through sacrificing some energy efficiency. In return, these magnetorquers will offer the fastest de-tumbling of any satellite in this mass class, allowing the users to start their operations in the shortest amount of time. The MTQ800 Magnetorquers feature an inherently safe, passive detumbling mode, which works without any external controller.
Compatibility
The MTQ800 series is compatible with AAC Hyperion’s portfolio of Attitude Determination and Control products.
Adaptability
Dipole moment directly controllable, in steps of 1 mA.m². In addition the controller can be tuned for faster/slower operation.
Heritage
The MTQ800 magnetorquer series has been flying on numerous missions since 2020 and is at TRL 9. It is based on AAC Hyperion’s experience in design and development of magnetorquers for CubeSats which have been flying since 2017.
