Magnetic Torquers interact with Earth’s magnetic field and create control torque, which can be adjusted to the required value. Combined with one or more reaction wheels, they provide all the control needed to maintain the spacecraft’s attitude, from Low Earth Orbit up to Geo-Stationary Orbit. Unlike thrusters torquers do not need valuable consumables, are low power components and highly reliable.
Although torquers appear to be relatively simple devices, they require thoughtful design and careful assembly. Our qualification and acceptance testing ensures that there is virtually no potential for degradation neither on the ground nor on-orbit. The torquer’s most critical component – its core material – has been treated to ensure optimal magnetic properties. Each unit is totally encapsulated and, except for the core, made from nonmagnetic space-grade components.
ZARM Technik Magnetic Torquers supported more than 50 international satellite missions. Not a single magnetic torquer out of over 170 units has ever failed. For more than 12 years we produce and improve intelligent technical solutions to reduce space mission costs. Our experience led to an outstanding flight heritage and satisfied clients all over the world.
