| 摘 要： | 简要介绍了GPS动态测量系统的组成及存在的缺陷。提出了采用滑窗多项式拟合方法进行航迹推算的数学模型，通过改变系统信息流向、重新组织下发数据报文结构等一系列技术措施来提高航路数据的拟合精度。仿真结果说明，该方法计算量小、速度快、精度高，利于飞机航迹的实时预测。

| Abstract: | This paper introduced the constitute and the shortages of GPS dynamic target measurement system in short.A dead reckoning mathematical model for sliding window polynomial fitting is proposed for raising the fitting accuracy of the route data,with changed the flow of data collection on the airplane and based on the sliding-window polynomial to extrapolate the airplane track.Meanwhile we re-organized the data structure.The simulation results demonstrates that the method has advantages of small calculation qua... |
