In this paper, a kind of low frequency sensor is designed. The multi-system satellite navigation receiver is located in the middle and the magnetic track composite receiving array is located in the surrounding area and is arranged in a heterogeneous form. Multiple arrays can be used for medium wave homing, long wave navigation and long wave timing reception. On the basis of analysis, simulation, design and experiment, this paper puts forward a clear thought structure and implementation method, which has a strong practical reference value in the research and development of communication and navigation equipment in the fields of E-navigation, Vessel Traffic Service, and unmanned small platform and so on.
