基于国产GBAS的咸阳机场CAT Ⅱ/Ⅲ精密进近引导飞行试验
CAT Ⅱ/Ⅲ precision approach guidance flight verification at Xianyang airport based on domestic GBAS
摘要
Abstract
Ground-Based Augmentation System(GBAS)can improve the accuracy,integrity,continuity and availability of satellite navigation,making it possible for aircraft to achieve safe and efficient approach and landing in complex weather and harsh environment,which can meet the high-precision navigation needs of civil aviation such as precision approach and landing guidance.At present,the GBAS Category Ⅰ(CAT-Ⅰ)service level has been verified and applied,but its service level,such as positioning accuracy,still can't fully meet the needs of civil aviation.The technology and application of GBAS Category Ⅱ/Ⅲ(CAT Ⅱ/Ⅲ),which have better service level,are still under development and validation.In order to improve the efficiency and safety of civil aviation operations,there is an urgent need to carry out flight verification activities based on CAT Ⅱ/Ⅲ.Currently,GBAS is mainly based on single-frequency GPS,which is very limited in terms of system availability,safety and autonomy,so it is necessary to develop an autonomous and controllable GBAS system which is compatible with BDS.This article designs a flight verification scheme,which has completed the GBAS flight verification for CAT Ⅱ/Ⅲ blind approach and landing guidance at Xi'an Xianyang Airport by using the domestic GBAS system.The test results show that GBAS compatible with BDS has the ability to support CAT Ⅱ/Ⅲ precision approach and its performance is far superior to the traditional instrument landing system.This achievement provides a strong guarantee for the safety of air transporation in China.关键词
