摘　　要：高精度实时外测数据是实施安全控制和数字引导的重要信息源,而布站几何对外测系统的精度有重要影响。为提高光电经纬仪的实时弹道解算精度,本文提出一种基于测量方案的布站优化模型。通过直接建立实时测量方案和布站模型之间的关系,提高实时测量精度和减小方案间的精度差异。采用高效的多目标寻优算法获得了最佳布站方案。常规布站优化模型结果比较,该优化模型的实用性强,能够显著提高实时弹道的解算精度。High accuracy exterior ballistic measurement data is an important source of information for safety control and digital guide while station distribution geometry has a strong impact on the accuracy.To improve the trajectory parameter accuracy of photoelectric theodolites,a station distribution geometry optimization model based on trajectory computing scheme is presented.Real-time measurement schemes are considered in the optimization model to improve the measurement accuracy and reduce the difference between processions of measurement schemes.The optimization problem is solved using a high efficiency multi-objective optimization algorithm to gain an optimum station distribution.Numerical design results and comparison with conventional models show that the model is highly practical and significantly increases the accuracy of realtime data.
