放眼全球化的当今社会，航空交通密度日益增大。机场运营繁忙，部分枢纽型机场的吞吐量逐渐趋近饱和。这种现状对先进的机场场面导向和控制系统提出了更高的要求。与传统的机场导向和控制系统SMGCS（Surface Movement Guidance and Control System）相比，先进的机场场面导向和控制系统A—SMGCS（Advanced—Surface Movement Guidance and ControlSystem）功能分为四部分：监视、路由、导向及控制。将对A—SMGCS的应用背景和发展状况给出较为全面的调研总结[1]，并结合ICAOA—SMGCSManual[3]论述对A—SMGCS提出详细功能需求．最后在此基础上提出A—SMGCS的系统功能架构．%Due to an increasing air traffic density all around the mordent world, some of the airport operations, with a SMGCS （Surface Movement Guidance and Control System） performance, are suffering overloads to their capacities. This project intends to search for a solution for the above difficulty. Compared with SMGCS, A-SMGCS （Advanced-Surface Movement Guidance and Control System）is facilitated with promoted functions spited as guidance, routing, navigation, and control. This paper gives a conclusion covering the investigation into the A-SMGCS application and development[1]. Additionally, system performance requirements are outlined based on ICAO （International Civil Aeronautics Organization） A-SMGCS Manual[2]. Finally, the A-SMGCS system architecture is developed in the paper. The introduction of A-SMGCS is capable to improve the airport operation efficiency and reduce the accident rate.
