摘　　要：在导弹系留飞行试验中,实时显示载机和目标轨迹的电子地图可以为试验指挥员提供直观的飞行态势和决策依据。由于试验数据敏感性,地面监测软件无法与互联网联通,导致无法采用在线加载的方法创建地图。提出了一种用于导弹飞行试验的百度地图离线加载方法。首先,获取离线瓦片图,并采用VC和JavaScript混合编程实现百度地图的离线加载与显示;其次,采用离线坐标转换算法将GPS输出的WGS84系下的位置信息转换至百度坐标系;第三,设计开发了轨迹量测与目标引导软件,实现了离散地图中目标编批信息和轨迹信息的实时显示,也实现了基准点标注、测距以及电子围栏等功能;最后,跑车试验表明离线坐标转换算法的精度达到10 m,同时也验证了离线地图加载的正确性。In the tethered flight test of missile,the electronic map showing the trajectory of aircraft and target in real time can provide intuitive flight situation and decision-making basis for test commander.However,due to the sensitivity of the flight test data,the ground monitoring software usually can’t connect with the Internet,as a result it’s impossible to load map online via the Internet.An offline loading method of Baidu map for missile flight test was presented.Baidu map was loaded and displayed offline by employing offline tile map and mixed programming of VC and JavaScript;The off-line coordinate transformation algorithm was used to transform the GPS position information from WGS84 system to Baidu coordinate system;The trajectory measurement and target guidance software was developed,which can not only display the batch information and trajectory of target in the discrete map in real-time,but also realized the functions of benchmark mark,distance measurement and electronic fence.Car test shows that the accuracy of the offline coordinate transformation algorithm is up to 10m,which show the correctness of the proposed method.
