摘  要:
基于GPS技术和嵌入式系统技术,设计了可实现自动规划边界、自动规划航道、计算农田面积、实时显示飞行轨迹和语音提示的农用飞机作业导航系统。阐明了系统硬件平台结构和QT交叉编译过程,研究了系统各项功能的实现算法。运用最小二乘法实时预测了高速运行环境下的定位数据,有效减小了高速运动产生的GPS定位延迟。在选定地块手持导航系统进行功能模拟,实现了作业导航系统的设计功能。

摘  要:
Based on the GPS technology and the embedded system,a multifunctional agricultural aircraft navigation system was designed.It combined the functions of automatic depiction of the farm outline,automatic trace planning,farm area calculation,real time trace-display and voice prompts.System hardware platform and QT environment were introduced,and the system function algorithm was discussed.The least square method was used to predict the positioning data in high-speed environments,it effectively reduced the positioning delay generated by the high-speed motion.Designing functions were achieved with the navigation system in certain field.
