Abstract Aimed at the metrology support requirements of weapons found north orientation equipment, on the basis of analysis about the technology at home and abroad, the calibration technology of gyro north-finder is studied. A North benchmark with self-check function is designed, which also sets up three north benchmarks, one is collimation normal north benchmark, the other two are infinity target north benchmark. The system has realized the calibration for different types of gyro north-finder. A northbound error correction method based on north benchmarks correction principle is proposed, which can monitor the drift and deformation of the north benchmark, and can realize the self-calibration of the whole north benchmarks. Infinity target location technology is adopted to establish the alignment model based on the known target azimuth, which solves the problem of accurate reset of gyro north-seeker rotation center. The astronomical orientation method is used to assign north to three north benchmarks. The precision of the introduced three northward azimuthal angles are better than ±0.5″. The practical application shows that the system is reasonable in design, reliable in use and stable in performance, it can be used as the standard equipment for measuring gyro north-finder.
