Problems solved by technology

[0003] The traditional inertial platform is a separate structure of the platform body and the control power supply circuit, with large size, heavy weight, and complex cable network; the space utilization rate that cannot be swept away by the inner ring that does not need to rotate 360° in the platform body is low; the structural parts and circuits are not Dense design; the degree of modularization is low, and the circuit boards are connected by more flying wires or motherboards that occupy a large space; there is a ring-shaped conductive device terminal board at the end of the shaft, which increases the radius of gyration of the ring frame and saves space. low utilization
