基于椭球的航迹点坐标推算
|
摘要
准确有效的航迹推算不仅能保证空域的安全畅通、资源的合理利用提高运行效率的提高,还可用于飞行过程中接收机自主完好性监测(RAIM)的可用性预测,保证飞行安全.针对国际民用航空组织(ICAO)建议的机载导航系统世界标准WGS-84坐标系,分析了基于WGS-84的文森特嵌入系数法,并利用文森特大地主题正反算推算巡航阶段的航迹点坐标以及过点时间,仿真实验验证了大地主题正反算的准确性并通过实际飞行数据验证了航迹推算算法的可靠性.
Accurate and effective track points prediction not only can ensure the safety and stable transition of airspace,make use of resources in a sensible manner to improve operational efficiency,but also can be used to the availability of RAIM prediction during flight for the sake of flight safety.The WGS-84 coordinate system recommended by the international civil aviation organization(ICAO)is the world standard for airborne navigation systems.The WGS-84-based T.Vincenty embedded coefficient method is analyzed to calculate the coordinates of the track points and the time of the crossing point of the cruise phase by means of T.Vincenty method.The simulation validates the accuracy of the land subject matter back and forth calculation and verifies the reliability of the track points prediction through the actual flight data.
