1. An EM receiver system for measuring EM signals while being transported by an associated vehicle, comprising
a base part arranged for connection to the associated vehicle,
a EM receiver coil comprising a plurality of windings of an electrical conductor and being arranged for measuring an EM signal, further comprising a coil support fixed to the electrical conductor,
a suspension system comprising
first and second gimbal axles defining first and second gimbal axes arranged in one plane,
wherein the first and second gimbal axles are arranged within a periphery defined by the EM receiver coil,
a central element arranged in a central part of the EM receiver coil and connected to both of the first and second gimbal axles, so that the first and second gimbal axes intersect in a central part of the EM receiver coil,
a first set of joints fixed to the coil support and a second set of joints fixed to the base part, so as to allow the EM receiver coil to pivot around the first and second gimbal axes, and
a spring system serving to provide a self-righting effect on the EM receiver coil around each of the first and second gimbal axes.
