A magnetorquer or magnetic torquer (also known as a torque rod) is a satellite system for attitude control, detumbling, and stabilization built from electromagnetic coils.

Magnetorquer rods are a method of controlling the attitude of a spacecraft either directly, by interacting with the local Earth’s magnetic field or, more usually, in combination with reaction wheels.

This paper describes the design and construction and testing of GT-1’s torque rods and will serve as a resource to help guide future torque rod iterations. The first section details the equations and mathematics behind torque rods.

MAGNETORQUER RODS Magnetorquer the planet’s local magnetic field. They can be used on their own or, more usually, in combination rods are a method of controlling the attitude of a spacecraft in orbit by facilitating the dumping of excess …

Oct 1, 2013 · Torque rods rely on the change in direction of the Earth's magnetic field, which is especially problematic in equatorial orbits because (to first order) the field has a constant inertial direction. Equating the control torque with the rigid-body rotational equations of motion: μ ×B = τ = Iα + ω ×Iω μ × B = τ = I α + ω × I ω.

May 17, 2023 · Magnetorquer rods, also known as magnetic torquers, are devices that use magnetic fields to control a satellite’s attitude. They are made up of a ferromagnetic core and a set of coils that generate a magnetic field.

Magnetic torque rods, or magnetorquers, are a type of electromagnets composed of a long range of wire looped around a magnetic core. When a current is run through the wire, a magnetic dipole moment is generated which interacts with the external magnetic field of the earth.

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.

Magnetorquers magnetic field or, more usually, in combination with reaction wheels. This secondary method rods are a method of controlling the attitude of a spacecraft either directly, momentum in the reaction wheels without the need for a complex propulsion system.

Aug 21, 2019 · Magnetorquers (also known as magnetic torquers or torque rods) are used in small satellites to provide attitude control – maintaining the satellite’s orientation with respect to an inertial frame.
