摘　　要：从RTK系统特点出发,分析了RTK测量误差来源,探讨各类误差来源的影响特征与规律。在探讨与无线数据链有关的误差中,详细研究了差分信号调制解调误差影响、外界环境干扰影响与纠错算法。最后,提出了相应的技术措施与对策,展望了RTK技术发展的未来。This paper analyzes the error sources of the RTK surveying based on the RTK systems peculiarity. The influencing characters are discussed on all error sources. Exploring the error in relation to the wireless data-chain, the error influencing and corrective arithmetic is researched detailedly into the modulating-demodulation error in difference signal, influence of the outside environment. The author finally bring forward the technical measure and countermeasure with the forecasts developmental trend of the RTK technology.
