RTK应用及成果精度分析
Application of Real Time Kinematic (RTK) Technology and Its Result Precision Analysis
【摘要】 为验证RTK作业的精度和可靠性,选择具有GPS静态控制网成果的平地、丘陵和山地三个测区作为试验区,根据不同参数转换和高程拟合方法测定的成果,与已知的GPS静态成果和水准高程进行比较,结果发现:在平地、丘陵、山地三种地貌条件下,使用相同的参数转换方式和高程平面拟合方式,其成果差别不大;存储方式对观测精度有一定的影响,一般情况下平滑存储成果的可靠性高于一般存储成果;使用四参数转换的成果较七参数转换的成果平面精度要高;使用平面拟合的高程精度略高于使用曲面拟合的高程。根据对测量精度及可靠性的分析结论,提出在勘探工程中RTK的作业方法及注意事项。
【Abstract】 To validate precision and reliability of the RTK operations,GPS static control network data possessed 3 surveying areas of flatland,hills and mountain land were selected as test areas,compared surveying results based on different parameters transformation and elevation fitting with known GPS static and leveling results have found under the above 3 relief conditions,to use same parameters transformation and elevation planar fitting,their results varied slightly from each other.Data storage forms have certain impact on accuracy of observation;generally,reliability of smoothing storage form is higher than general storage form.Planimetric accuracy of results from 4 parameters transformation is higher than results from 7 parameters transformation.Elevation accuracy from planar fitting is slightly higher than from surface fitting.According to surveying precision and reliability analytical conclusion,RTK operational method and matters needing attention in prospecting projects put forward.
