摘　　要：为提高自身不能提供姿态调整手段的惯性平台在高精度转台上的动态试验精度,设计了独特的安装及标校方法。利用新设计的方位标定装置,使用光学经纬仪及电子水平仪将方位标定装置上的光学六面体的法线与高精度转台的方位轴线取齐。然后,拆下方位标定装置,摇摆台置零,安装水平调整机构。将电子水平仪放置到水平调整机构的安装平板上,调节水平调整机构,将安装平板调平。安装惯性平台,将电子水平仪放置到惯性平台的水平基准平台上,再次调节水平调整机构,使电子水平仪的输出与转台示值一致,从而达到惯性平台与高精度转台水平取齐的目的。随后以光学经纬仪为过渡基准,将惯性平台的光学方位基准与高精度转台方位取齐,从而达到惯性平台与高精度转台坐标系对齐的目的。A unique fixing and calibration method was designed for increasing the dynamic test precision of the inertial platform on high precision turntable. First, with the new designed azimuth calibration device and using optic theodolite and electronic gradienter, the normal line of optical hexahedron on azimuth calibration device was adjusted to be in alignment with the azimuth axis of high precision turntable. Then we dismounted the azimuth calibration device. After this, we set the turntable to zero, and fixed the electronic gradienter on the fLxing plate of level regulator. When the indicating values of electronic gradienter were identical with that of high precision tumtable by means of adjusting level regulator, the level of inertial platform was in alignment with the level of high precision turntable. Then, taking optic theodolite as transition benchmark, the optical azimuth benchmark of inertial platform was adjusted to be in alignment with the optic azimuth axis of high precision turntable. In this way, the calibration is realized.
