动态优化不等精度经纬仪交会方法

在多台不等精度经纬仪交会测量系统中,为提高数据的可靠性和精度,根据异面交会原理,提出空间定位精度及其误差的模型;提出采用定常异动算子算法和普通加权平均法相结合的处理方法;对该算法进行数学仿真,计算分别使用定常异动算子和普通加权平均法的交会角区间,并在实际任务中加以应用。试验结果表明,采用合理的算法对多台不等精度经纬仪进行交会测量,增加了测量基线数量从而提高了整体数据的稳定性,同时提高了测量精度。

Dynamic Optimized Intersection Method Between Theodolites with Different Precision

In the intersection measurement between theodolites with different precision,in order to improve the reliability and precision of the measure data,a position model and its error model are presented.A process method combined context independent variable behavior and weighted average is analyzed.The algorithm is simulated,the intersection angle area is calculated to judge whether context independent variable behavior algorithm or weighted average algorithm is chosen and applied in task.The result shows that the multi-theodolites with different precision system can increase measure baselines and improve the reliability with the decrease of measurement error effectively.
