Low Remanence Torquers and Coils
The simplest method of changing the attitude of nanosatellites in LEO is using magnetic torquer rods.
CubeTorquer is a nanosatellite magnetic torquer that uses a specially treated ferrous core with ultra-low remanence and high linearity. It can be used for detumbling, coarse attitude changes and to desaturate reaction wheels.

- When it comes to magnetic control on satellites, it is most important to remove all unwanted magnetic disturbances. One of the most common disturbances is remanent magnetic dipoles left in parts of the satellite after a torquer has been pulsed. We use a highly specialized material for the ferrous core of our rods, which we treat to give our rods ultra-low remanence.
- In small satellites, compactness is a strong requirement. The way the standard CubeSat boards are stacked makes it difficult to have three rods to form a 3-Axis system. We offer a low-profile air-core coil that slots into the stack between the CubeSat PCBs. In this way, we can create a very compact 3-Axis magnetic control system.
