The MTQ400 from LusoSpace is a Magnetorquer with a magnetic dipole moment of +/- 400 AM^2 and a linearity error of less than 1.5 %. It has a residual magnetic moment of less than 0.5 % and a time constant of less than 250 ms. This dual coil magnetorquer requires a supply voltage of +/- 28 V and consumes less than 15 W of power. It is radiation hardened up to 100 kRad and is fully qualified for space applications up to a TRL 6 according to ECSS (ESA) standards and MIL standards. This magnetorquer generates a magnetic moment that can be used for S/C attitude control or reaction wheels offloading. It has a mass of 7 Kg and measures 950 x 80 x 80 mm. It is ideally suited for middle/large-sized spacecraft.
