Abstract: An electromagnetic receiver system with an EM receiver coil is for measuring EM signals while transported by a vehicle, e.g. a helicopter. A base part serves for connection to a towing system. A coil support is fixed to the electrical conductor of the EM receiver coil. A suspension system has gimbal axles defining gimbal axes arranged in one plane. The gimbal axles are arranged within a periphery of the EM receiver coil. A central element is connected to the gimbal axles, such that the axes intersect in an EM receiver coil central part. Joints allow the receiver coil to pivot around the first and second axes. Springs provide a self-righting effect on the coil around the axes. A precise calibration of centre of mass of the suspended receiver coil can be obtained by adding masses to cause the centre of mass to coincide with the geometric intersection between the axes.
