The present application provides a method, system and device for positioning and guidance. The method may include: measuring the magnetic field value of the electromagnetic signal emitted by the transmitting end; calculating the numerical gradient of the magnetic field value based on the measured magnetic field value; guiding the device to adjust the position and attitude according to the numerical gradient of the magnetic field value, so that the position of the device and the transmitting end is alignment. Through the present application, the receiving end can search according to the gradient direction of the electromagnetic field distribution, so that accurate registration of the transmitting end and the receiving end can be realized. In addition, the receiving end realizes position calibration based on the numerical gradient of the electromagnetic signal, which can effectively solve the defect that the electromagnetic signal is easily interfered by the environment (such as metal objects), and improve the accuracy of guidance and positioning.
