航站楼流程设计及管理与中枢机场运营

机场尤其中枢机场是各种地面交通工具和空中运输以及空中运输之间的交换点。作为中枢机场运营管理者，应当致力于保证旅客进出机场有最好的通道，致力于为旅客交通运输方式的改变提供一切便利条件，以此有效节省旅客时间，降低其出行成本，从而提高机场的可利用性，提升机场通过能力和辐射能力。这其中航站楼流程的设计及管理，无疑应当成为中枢机场运营的核心，直接影响到中枢机场运营战略目标的实现。     

METHOD FOR DETECTING AND REPAIRING CYCLE SLIPS IN GPS NAVIGATION

A new method is proposed for detecting and repairing cycle slips in GPS navigation based on the dual frequency observations. It can be implemented through the following three steps: (1) The integer ambiguities of the current epoch are substituted by that of the previous epoch, so the ambiguity parameters are removed from the observation equations. (2) The abnormal observations are detected using the quasi accurate detection (QUAD) method and the satellite pairs of these abnormal observations are determined. Then the coefficient matrix of these satellite pairs is recovered. (3) The cycle slips of these satellite pairs are calculated using the LAMBDA method and integer ambiguities of the current epoch can be determined by adding the cycle slips into the integer ambiguities of the previous epoch. The key of this method is that the abnormal observations must accurately he detected, i.e. , the satellites having cycle slips must correctly be judged. Finally, compared with other methods the feasibility of the method is verified.

NM3500型盲降下滑设备故障分析

本场盲降设备是从挪威NORMARC公司引进的3513／3531B型，设备自1997年安装、运行以来工作正常，提供了良好的导航保障。但其间也出现过一些故障，在这里讨论两个典型故障。
