摘要 [目的]为GPS快速定位技术在城镇地籍调查中的应用提供依据。[方法]山亭区城镇地籍调查控制测量项目采用D级GPS控制网作为测区首级控制网,利用4台Trimble 5700 GPS双频接收机进行快速静态测量,选用22个点构成骨架网,进行优化设计,利用TrimbleDINI12电子水准仪进行GPS四等水准联测。[结果]通过精度统计及分析,利用快速静态定位测量结合GPS水准成果,能满足C级以下GPS控制测量的要求,利用一定数量和分布均匀的GPS水准点进行高程拟合,能达到四等以下水准测量的精度。[结论]在城镇地籍调查中采用GPS快速定位技术建立首级控制网,取得了很好的经济效益。 [Objective] The research aimed to provide references for the application of GPS speed static positioning technique in urban cadastral survey.[Method] The D-grade GPS control network was used as first class control network in measurement volume in the Shanting district urban cadastral survey.Four Trimble 5700 GPS dual frequency receiver was used for fast static survey.Twenty-two points were choosed to compose skeleton network and to exercise optimal design.GPS fourth-grade leveling joint control survey was carried out with Trimble DINI12 electronic level.[Results] The results could meet the demand under C-grade GPS control measurement by precision statistics analysis,using fast staticposition measurement combined with theGPS leveling data.And it could meet the demand under GPS fourth-grade leveling accuracy using a certain amount and well distributed GPS leveling points for height fitting.[Conclusion] First class control network was established in urban cadastral survey with GPS speed static positioning technique,and good economic benefit was obtained in the study.
