CubeSat Magnetorquer SatBus MTQ

Magnetorquers „SatBus MTQ“, designed by NanoAvionics, are a set of two x and y axis magnetorquer rods and one z axis magnetorquer coil which are mounted on a PC-104 form factor PCB to enable nano-satellite attitude control.

The system is designed as a part of NanoAvionics „SatBus“ nanosatellite platform but can be used with any third party ADCS controllers that can provide 3 PWM controlled voltage outputs to each torquer coil.
