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。
Under the environment of STK visual simulation, the system introduced the geo-data through the establishment of digital model of rocket and measurement and control equipment, and created the environment of rocket launch control station. On this basis, using the rocket trajectory theory, the tracking arc, TAER and shadow angle of each monitoring and control equipment are analyzed. Gaussian-Markov least square method is used to estimate the intersection accuracy of multiple equipment. The method of GDOP and equipment constraints is proposed to evaluate the rationality of station monitoring and control. The genetic algorithm is used to select the best station in a given area for stations that do not meet the requirements of monitoring and control. The system can also be applied to other areas of the cloth station evaluation and analysis.
