摘要
精确定位是精准农业的关键技术之一。本文通过使用计算机串口对GPS信号进行接收,对WGS-84坐标进行高斯-克吕格投影坐标变换,对GPS单点定位精度进行了试验研究。得到了先进可行的试验方法,编制了计算机程序,可用于我国精准农业精确定位技术应用的试验研究。
Accurate positioning is one of key technologies of Precision Agriculture. Author used advanced technology to receive GPS signal data by computer series port, convert WGS-84 coordinate system to Gauss-Kruger projection and test on absolute positional accuracy. And compute program was designed for future experimentation of accurate positioning in precision agriculture developments of China.
