GPS15州港航局清江水布垭至恩施段航道工程施工图阶段工程勘测测量技术总结5观测1.点间均采用边连式连接，施测采用静态GPS方式。 2.共布设了15个点，3个已知点，构成一个独立的E级GPS控制网，观测分1个时段观测，每个时段观测120分钟。 3.GPS网观测、记录严格按照以下要求执行a.天线对中误差3mm，天线整平，圆气泡居中。 b.丈量天线高度,均从天线互为120方向的三面丈量三次,在三次较差不大于3mm时,取平均值为最后结果。 结束观测时,再丈量一次天线高,以作校核。 c.在观测过程中,自始至终有人值守,并经常检查有效卫星的历元数是否符合要求,否则及时通知其它两台仪器,延长时段时间,以保证观测精度。 作业期间，作业员不得离开现场，不得在接收机旁使用对讲机，防止其他人和物体靠近天线，遮挡信号。

g.本次E级GPS控制网静态测量基本技术规定按下表执行:等级项目E级卫星高度角()15时段长度静态(min)120平均重复设站数(次/每点)1.6同时观测有效卫星数(个)4颗以上数据采样率(s)15GDOP6清江水布垭至恩施段航道工程施工图阶段工程勘测测量技术总结6同步观测接收机数6平差计算外业观测后及时输入计算机,并进行外业数据的检查。 基线解算采用Campass华测静态数据处理软件。 基线处理成功后，进行WGS-84坐标系下的自由网平差及三维约束网平差。 GPS点的点位中误差最小为4.5mm（点号为GPS13）；最大为49.3mm（点号为GPS9）。 最弱边（GPS5-GPS6）相对中误差为1/54035，最弱点（GPS9）点位中误差为49.3mm。 6.2高程控制测量高程控制测量采用三角高程代替四等水准进行观测，平差计算使用清华三维高程网解算软件。 七.地形图测量1:500地形图测量采用全站仪极坐标法采集野外碎部点数据,观测要求按JTJ203-xx水运工程测量规范执行,由于测区80%的区域地势陡峭、通行困难，全站仪的免棱镜功能发挥了极大功用，在陡壁面上均采集了数据。 数字化测图以基本控制点、图根点为测站点,不足时以测距支导线、极坐标法支点等补充测站点；全站仪采集地物点、地形点的最大距离小于300m，为便于后期施工图设计的需要，地形图上高程注记点原则上全部保留野外采集的所有原始地形数据，地形图测量的内容及表示符号严格按规范和图式执行。 地形图图层分层以软件默认设置为主。 内业使用南方测绘公司开发的CASS7.1成图系统软件根据野外草图进行处理,最后生成DWG格式的数字化地形图。 八.质量保证体系我公司测绘技术力量雄厚，仪器设备先进齐全，人员分工明确，对测绘成果清江水布垭至恩施段航道工程施工图阶段工程勘测测量技术总结7质量制定了一套便于管理、便于操作、便于监控并适合我公司的质量保证体系。
