基于VRS技术的RTK-GPS接收系统设计

    Development of RTK-GPS receiver system based on VRS technology

    • 摘要: 为了满足精细农业中对高精度定位数据的需求,该文使用低成本的RTK-GPS OEM板和CDMA无线通讯模块,设计开发了一套可采用VRS差分的GPS接收系统。试验结果表明,该系统性能稳定;在快速静态定位时,不同天气条件下的内符合精度为2~3 cm(95%),可满足精细农业中高精度快速定位的需求;在动态定位试验时,通过与美国Trimble公司的AgGPS332进行对比,2条轨迹间的最大偏差不超过5 cm,可作为高精度的位置传感器用于农业车辆自动导航。
