 As would be the case with real-world spacecraft, magnetometer readings inside Orbicraft are not determined exclusively by the external geomagnetic field. Other instruments (mainly including reaction wheel motors and the power supply system) can interfere with readings. For that reason it is not recommended that the magnetometer be located immediately next to those devices. As would be the case with real-world spacecraft, magnetometer readings inside Orbicraft are not determined exclusively by the external geomagnetic field.
