摘要
本文从复杂地形区的特征出发,分析了实时动态差分定位(RTK)测绘过程中存在的主要影响因素,包括卫星可见数、多路径误差、基线长度与通信链路可靠度,并构建了多因子误差仿真模型。通过实地监测数据与模型计算结果对比,验证了模型的准确性与控制措施的有效性。进一步提出了适用于复杂地形的施工技术体系,包括基准站布设优化、信号补偿与多源融合技术、科学的外业观测策略等。研究结果表明在综合技术手段支持下,RTK技术可实现复杂地形区的高精度稳定测绘,具备良好的工程应用价值。
This paper analyzes the primary factors affecting Real-Time Kinematic(RTK)surveying in complex terrain,including satellite visibility,multipath errors,baseline length,and communication link reliability.A multi-factor error simulation model was developed and validated against field monitoring data,confirming its accuracy and the effectiveness of corresponding control measures.A comprehensive technical framework tailored for complex terrain is proposed,encompassing optimized base station deployment,signal compensation,multi-source data fusion techniques,and scientific field observation strategies.The results demonstrate that,supported by these integrated technical measures,RTK technology can achieve high-precision and stable mapping in complex topographic areas,proving its substantial value for engineering applications.
