摘要
目前国内装备应用单位对陆用高精度激光惯导装备的使用维护保养不当或不规范对惯性装备性能的影响尚无准确的理论分析,为此,以某型陆用高精度激光陀螺定位定向系统为研究对象,结合国内惯性传感器技术水平现状,详细分析了陆用高精度激光惯导装备对维护保养的需求以及规范维护保养作业的重要性。该型产品通过定期通电和系统定标维护,故障产品性能恢复,维护保养前后的水平定位精度典型实测数据分别为8.35m(CEP)和2.9m(CEP),以期为国内同类装备的设计、生产以及部队使用提供参考和理论支撑。
At present,there is an insufficient understanding of the use and maintenance of the land based high-performance inertial navigation equipment domestically.Additionally,there is no accurate theoretical analysis on the effects of improper or non-standard maintenance on the performance of inertial equipment.In order to solve the problem,taking a certain type of land-based high-precision laser gyro positioning and orientation system as the research object,combined with the status quo of domestic inertial sensors,the demand for maintenance of land-based high-precision laser inertial navigation equipment and the importance of standard maintenance operations was analyzed in detail.After electricity maintenance and system calibration at regular intervals,the performance of malfunction equipment was restored.The test data shows that,the horizontal positioning accuracy of the system can be typically improved from 8.35 m（CEP）to 2.9 m（CEP）by maintenance.This paper can provide references and theoretical supports for the design and production of similar equipment in domestic,and utilization for army.
