NSS CubeSat Magnetorquer Rod
Magnetorquers offer a method of controlling the attitude of a spacecraft. This can be achieved either directly, by interacting with the local Earth’s magnetic field, or in combination with reaction wheels where they allow a method of dumping excess momentum in the wheels without the need for a complex propulsion system.
The use of a magnetic alloy rod produces an amplification effect over an air cored magnetorquer. This allows a system that uses less power, which is critical for CubeSat missions. The rods can enable a mission with increased manoeuvrability and reduced detumble rates.
CubeSat Magnetorquer rods are designed to be run directly from a switched 5 Volt power output from the on-board power control system.
