摘要
购买现成的差分GPS(DGPS)设备可以直接进行差分定位,但设备昂贵。简述了差分GPS(DGPS)定位原理以及 RTCM SC-104数据格式及其电文编码。提出了利用普通的GPS-OEM板建立差分GPS定位系统的设计方案。试验表明,这种 差分GPS定位系统可以提供2-5 m的平面定位精度,且具有设备简单、造价低及实用灵活等优点。
The purchasable differential GPS equipment can be positioned, but the cost of the equipment is higher. The differential GPS (DGPS) positioning principle is introduced, and RTCM SC-104 message content is also described. The design scheme of the pseudo-range differential GPS positioning system based on GPS-OEM is proposed. Test result shows that the positioning precision by this DGPS positioning system can reach to 2-5 meters; also, it is low cost and flexible.
