摘要
以边角网间接平差为例,对比分析了不同多余观测数条件下,观测值的平差值和中误差的变化,通过实例数据证明,增加多余观测数,观测值的平差值会出现微弱波动,平差值的精度会显著提高。对工程实践具有一定的指导意义。
In the corner network indirect adjustment as an example, a comparative analysis of differ- ent number of redundant observation conditions, the change in adjustment of observations and error, through the example of data improve that the increased number of redundant observation will make adjustmeng value appear weak fluctuation, the precision of adjustment value will increase significant- ly.
