When the wireless charging of unmanned aerial vehicles (UAVs) relay stations and that of the submarine base stations of underwater unmanned submarines (UUSs) were used, the spatial orientation deflection of electromagnetic coils often occured. To solve this problem, a magnetically coupled resonant wireless power transmission (MCR-WPT) system was built based on superconducting coils and copper coils. Firstly, the quality factor and resistance of superconducting coils and copper coils were measured. Secondly, the variation law of the transmission efficiencies of the high-temperature superconducting(HTS) MCR-WPT system and the copper experimental system were studied and analyzed when the spatial deflection was superimposed on the spatial orientation deflection. The results showed that the spatial azimuthal deflection under different lateral spatial deviations had different effects on the transmission efficiencies of the wireless transmission system. The application of superconducting coils for the full spatial misalignment interval under the MCR-WPT system resulted in a transmission efficiencies growth rate of 15.6%$\sim $35.5%. These advantages and laws created good application prospects for the provision of high efficiency and stability of wireless charging under strong spatial misalignment for devices such as UAVs and UUSs.
