| 摘 要： | 由于靶标布设是航天测控的重要问题之一,覆盖分析为靶标布设提供重要的参考依据.为研究靶标布设的规律特点,提高测控质量,提出了利用STK进行仿真分析.针对某个工程中的靶标布设问题,采用卫星携带相机的侧摆情况和相机类型的情况,对卫星过境的覆盖品质进行了分析建模.并运用MATLAB与STK软件进行联合仿真,得出6种模式下的覆盖结果.仿真结果表明,无论是否侧摆还是相机类型不同的情况下,卫星过境时长均只与所处纬度有关,与经度无关,并且纬度越高,覆盖品质越好.

| Abstract: | Target layout setting is one of the important issues in aerospace TT&C technology,and coverage analysis provides an important reference for it.In order to discuss the laws of target layout setting,the utility of STK for simulation analysis was proposed.Base on considering an engineering problem,the paper studied the side swing and types of camera carried by satellite,and subsequently analyzed the quality of satellite coverage,and built the model.Through co-simulation using MATLAB and STK,six kinds of modes of coverage results were derived.Simulation results indicate that neither the type of side swing nor athe type of camera can change this law: the duration and times of satellite transiting is related to latitude,and independent of longitude.Furthermore,the higher is the latitudes,the better the quality of covering is. |
