【 摘 要 】

Aimed at the metrology support requirements of weapons found north orientation equipment, a gyro north-seeker calibration system is designed. The system uses one plane mirror and two 1 m collimators to set up three north benchmarks at the same time, and they are assigned to the north. The accuracy of the introduced three northward azimuthal angles is as follows: ±0.20″, ±0.18″, ±0.17″. Between the three north benchmarks, the mutual check function can be realised. The system can realise the calibration of the gyro theodolite and gyro north-seeker with auto-collimation function and no auto-collimation function. The composition and working principle of the system are described in detail. After examination, the north-seeking precision accuracy of the system is 3″ (k = 2). It satisfies the metrological calibration of the gyro theodolite and gyro north-seeker whose north-seeking precision is below 12″. Through practice, the system is accurate, stable and reliable.
