基于GPS-OEM的田间信息采集仪定位精度分析

Accuracy Analysis on Positioning Accuracy of Field Information Acquisition Equipment Based on GPS-OEM

GPS定位信息是精细农业实践需要获取的重要信息之一,GPS-OEM板与精细农业中的信息采集设备相结合进行设计开发,既可以很好地实现定位数据与属性数据的融合处理,又使设备的体积减小、成本降低,已成为人们关注的焦点。为此,自行研制了一种基于GPS-OEM板的田间信息采集仪,重点介绍了GPS定位模块的软硬件设计,并对GPS定位精度进行了分析。试验结果表明,其最大定位误差为1.51m,可以满足精细农业田间信息采集的要求,为以后采集仪的进一步研究提供了理论基础。

GPS positioning information is one of the important information to precision agriculture. The design with the combination of GPS - OEM board and information collection equipment has become the focus of people＇s attention. Not only the fusion of the positioning data and attribute data can be realized, but also the volume and cost of the device can be reduced. So a kind of field information collecting equipment is developed based on GPS - OEM. In this paper, the software and hardware design of the GPS positioning module is introduced and the GPS positioning accuracy is analyzed. The results show that the maximum positioning error is 1.51 m can meet the need of precision agriculture field information collection. The theoretical basis is provided for further research.
