| 摘 要： | 为满足精细农业中农业机械自动导航对高精度定位数据的需求,阐述了GPS差分定位技术在精细农业中存在的问题,并介绍了CORS技术在精细农业中的重要地位。根据分析,采用低成本的GPS板卡和4G无线通讯网络模块,设计开发了一套基于CORS技术的低成本农业机械差分定位系统,并进行了系统静态内符合精度测试和动态误差测试。试验结果表明:该系统性能稳定,在晴天和阴天2种天气情况下,其静态定位内符合精度为7~8 cm(9 5%);通过多次测量求平均值,其动态定位数据与真实值的误差不超过1 0 cm,动态符合度高,可作为高精度的位置传感器用于农业机械自动导航。

| Abstract: | In order to meet the demand of the high precision data collection in agricultural machinery automatic navigation of precision agriculture , this paper describes the problems of GPS differential positioning technology existing in precision agriculture and shows the important role of CORS technology plays in the precision agriculture .According to the analysis , a low cost GPS board and 4 G wireless communication network module are adopted and a low cost agricultural machinery differential positioning system based on CORS technology is designed and developed .Meanwhile , the static inner preci-sion and dynamic error of the system are tested .The result of test shows that the system is stable and its inner precision of static positioning is between 7 and 8 cm(95%) in clear weather or overcast , and error between the dynamic positio-ning data and the true value is with 10 cm during several measures of average value so its dynamic conformity is high . Therefore , the system can be used as high positioning position sensor in agricultural machinery automatic navigation . |
