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 however, 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. They furthermore feature an inherently safe, passive detumbling mode, which works without any external controller.

The MTQ800 has been flying ever since September 2020.

The MTQ800 is at TRL 9.

All MTQ800 are Flight models. You may use them as Engineering models.

The MTQ800 delivery includes functional testing as well as workmanship testing (vibration only). Additional testing is available on request.
