基于3G网络的农业机械GPS差分系统的研究

Research on Differential GPS System of Agricaltural Machinery Based on 3G

介绍了GPS导航技术在精细农业中的重要地位,并阐述了GPS差分系统在农业上的应用现状,指出了现有农业机械GPS差分系统通讯链路中存在的问题和不足,提出了将3G网络作为通讯链路应用到GPS差分系统,并搭建了自基站经3G网络到农机的GPS差分系统。

This paper introduced the important status of GPS-navigation technology in the field of precision farming, and explained the current application situation of differential GPS system in farming. The paper pointed out the problems and defects in DGPS system , which is applied in farming machinery, and put forward to apply 3 G network to DGPS system as a communication link, and built a DGPS , where the data from the base station passed 3G network and finally arrived the farm vehicle.
