Embodiment Construction
[0024] In order to enable those skilled in the art to better understand the solutions of the embodiments of the present invention, the embodiments of the present invention will be further described in detail below in conjunction with the drawings and implementations.
[0025] First, refer to image 3 , is the overall layout system of the present invention, 1 is the short section of the battery, 2 is the control circuit part, 3 is the inertial measurement unit, and 4 is the probe guide shoe. The inertial measurement unit is composed of three gyroscopes, three accelerometers and three fluxgate sensors, and the mechanical layout refers to figure 2 . The acceleration sensor, inertial sensor, and magnetic sensor are precisely calibrated, and the three axes are highly consistent. According to the principle of inertial navigation, the strapdown inertial navigation method is used to measure the azimuth, tool face angle and inclination angle. The gyroscope is used to sense the thre...
