| Abstract: | The Virtual Reference Station(VRS)'s components,principle of operation and its advantages were discussed.A GPS receiver based on the VRS was developed,which included a microprocessor,an AC12 GPS module,a GSM module,a keyboard,a LCD and a USB flash disk.The GPS receiver could gain GPS corrections from the VRS system via GSM,and the DGPS data could be displayed real time on the LCD and be stored in USB flash disk.The experiments indicated that the developed GPS receiver based on the VRS could work stably.The results showed that the accuracy could be kept within 1.25 m(95%).It had good practicality for precision agriculture like soil sampling and area measuring. |
