基于监视数据修正的航空器飞行轨迹推算模型

飞行轨迹推算是空中交通流量管理的一个重要研究内容。在传统飞行轨迹推算方法基础上,针对航空器飞行路径的不确定性,构造了基于监视数据动态修正的航空器飞行轨迹推算模型。该模型综合航空器飞行性能和飞行计划、实时监视信息对航空器飞行轨迹、姿态进行推算。利用真实飞行轨迹进行验证,结果表明:本文模型推算的位置、高度信息更接近实际轨迹,并且符合实际飞行原则和空域使用规则,具有一定的参考价值和实用性。

Flight Trajectory Revised Prediction Model Based on Surveillance Information

Flight trajectory prediction is always the main research subjects in regard to air traffic management. Based on the traditional methods, for the flight path changing, the flight trajectory projection and revised by real-time surveillance information model was proposed. The model was integrated aircraft flight performance and flight plans, real-time surveillance information, revised projections and performance. Validated with real flight plan, the results show that: the proposed model is closer to the actual flight procedure. The proposed model is also in line with the principles and the actual airspace flight using rules. This model has a certain reference value and practicality.
