差分GPS技术在谷物测产系统中的应用

The Application of Differential GPS Technology in Estimation System of Grain Production

目前,在谷物测产系统中,开始应用动态差分GPS技术建立产量计算模型和小区产量分布图,以获得农作物小区产量信息。为此,介绍了GPS定位原理、方法以及动态差分GPS技术,并进行了差分定位试验和分析。差分GPS在谷物产量图生成中的应用表明,差分GPS技术能满足田间谷物测产的需要。

The dynamic GPS technology is used in estimation sytem of grain production.So introduced the locationing method and theory of GPS,dynamic GPS technology, did the experiment and analyzed about differential locationing.The application of differential GPS in grain production figure shows that differential GPS technology can meet the need of grain production estimate.
