| 摘 要： | 随着基于性能导航(RNP)飞行程序的成熟发展,多径误差抑制在差分增强系统中的影响也日益凸显。本文采用伪距频间组合差与伪距与载波相位组合差的方法分析了多径效应对类精密进近造成的误差影响。采取空域以及窄相关器多径抑制方法,减小测距容差,其结果完全满足RNP类精密进近的着陆要求。

| Abstract: | With the fast development of RNP flight procedure, the technology of mitigation of multipath interference in DGPS landing system become more and more important. Based on the method of frequency difference between the combination of pseudo range and carrier phase with poor combination, the paper analysis the errors made by the multipath signals for APV. Using airspace and narrow correlator technology, narrowing down the ranging errors, the result shows that it can fully meet the requirement of APV. |
