description The invention relates to the technical field of underground azimuth measurement while drilling. A solid vibratory angular rate sensor is adopted as a core measurement device, which can effectively reduce the volume of a measurement while drilling device and anti-impact vibration, adapt to measurement while drilling environment, and not be disturbed by the outside disturbance of an electric field and a magnetic field. The aim of the system is realized as follows: the measurement while drilling system comprises an exploring tube which is internally provided with a measurement bin; the measurement bin is internally provided with a triaxial acceleration sensor, a biaxial angular rate sensor and a treatment circuit; the triaxial acceleration sensor is used for measuring the gravitational acceleration in three directions and outputting the gravitational acceleration to the treatment circuit; the biaxial angular rate sensor is used for measuring moving angular seed in two directions and outputting the moving angular
