GLS飞行程序三维仿真系统设计与实现

Design and implementation of 3D simulation system of GLS flight procedure

为解决GLS (GBAS landing system)飞行程序二维航图显示不直观和实际飞行过程中飞行技术要求高、成本高、风险高等问题,基于三维地理信息系统(U-GIS)进行开发,提出一种GLS飞行程序三维仿真系统的设计方案。根据系统功能需求,对系统体系结构及功能模块进行设计,实现基础数据管理、航迹管理、信号覆盖等子功能。实验结果表明,该系统能够快速完成GLS飞行程序三维可视化仿真,可用于GLS飞行程序的辅助验证。

To solve the problem that the two-dimensional aeronautical chart of GBAS landing system(GLS)flight procedure is not intuitive and that high flight technical requirement,high cost,and high risk exist in the course of actual flight,a design scheme of three-dimensional simulation system of GLS flight procedure was proposed based on 3D geographic information system(U-GIS).According to the system functional requirements,the system architecture and functional modules were designed,and the sub-functions of basic data management,track management and signal coverage were realized.Experimental results show that the proposed system can rapidly achieve the 3D visual simulation of GLS flight procedures and can be used for auxiliary verification of GLS flight procedures.
