摘　　要：系统在STK可视化仿真环境下,通过建立火箭和测控设备数字模型,引入地理数据,创建了火箭发射测控布站环境。在此基础上,利用火箭弹道理论,分析出各测控设备的跟踪弧段、TAER、遮蔽角等信息,采用高斯-马尔可夫最小二乘法估计多台设备的交汇精度。提出了基于GDOP和设备约束条件作为测控布站合理性评估要素的评估方法,并采用遗传算法对不满足测控要求的站点选定了给定区域内的最佳布站方案。该系统还可以应用到其他领域的布站评估分析中。Based on the visual simulative environment of STK,the system has established the environment of disposition for launching the rocket,through setting up mathematical model of the rocket and the facilities,introducing the geographical data.On this basis,by utilizing the rocket theoretical trajectory,we analyse lengths,AER,defilade angle,etc.,and adopt Gauss-Markov’s least square method to estimate more intersection precision of the facilities.A new method to evaluate the disposition based on GDOP and constraied condition of facilities is presented,and we have elected the optimal disposition in the given area with the genetic algorithm.The system can also be applied in the disposition in other domains for evaluating and analysing.
