2、近，终于鹅公镇田心村委会山塘垇附近，与A8标起点（K201+800）相接，路线全长3.27km。路线整体呈南北走向（另鹅公枢纽及定南联络线3.126公里）。地理位置构造低丘沟谷地貌，地势稍有起伏，海拔高程250-37米。水系发达，植被茂盛，通视条件差，野外作业困难。2、平面坐标系统平面坐标成果属西安80坐标系统，中央子午线为东经115°30。3、高程系统1985年国家高程基准。二、作业情况1、作业时间2015年01月27日开始GPS复测和导线点加密作业，于2015年01月29日全线贯通，并及时提供了阶段性的数据处理成果，以保障测设工作的顺利进行。2、作业依据（1）国家技术监督局、国家

3、建设部2007年联合发布的工程测量规范 （GB50026-2007）；（2）国家交通部2007年颁发的公路勘测规范(JTG C10-2007)；（3）国家交通部1998年颁发的公路全球定位系统（GPS）测量规范(JTJ/T 06698)。3、人员、设备配置本次作业由专业测量人员6名人员参加，GPS控制投入了5台经检测合格的上海华测双频双星X90 GPS接收机进行GPS静态采集。二、控制测量（一）网的布设本GPS是沿公路隧洞线路布设的，其形状为狭长的带状延伸型。考虑到线路施工阶段的需要，保证每两个相临点相互通视。由于本GPS控制网带状分布的特殊性，决定采取边连接方式整体布网，大多布设成以大地四边

4、形相连的网形，网形结构较好。GPS网相邻点间基线中误差按下式计算：式中(mm)为固定误差；(ppm)为比例误差系数；(km)为相邻点间的距离。GPS-E级网的主要技术要求应符合表1规定。相邻点最小距离应为平均距离的1/21/3；最大距离应为平均距离的23倍。GPS网的主要技术要求级别平均距离(km)(mm)(1×10-6)PPM最弱边相对中误差E级0.2510201/45000（二）数据采集采用5台GPS接收机以静态相对定位作业模式进行野外数据采集，基本技术要求为：卫星分布几何图形精度衰减因子PDOP值7，同步观测卫星4颗，卫星高度角15，观测时段长度45min，数据采样间隔10秒。

5、（三）基线处理1、基线解算基线码，对流层改正采用Hop field模型，电离层改正采用标准模型，部分线采用人工干预方式解算。对每天的观测结果都及时进和了解算和质量检核，最终基线结计算采用上海华测公司研制的“compass”软件，使用广播星历C/A果均采用双差固定解，并且衡量基线解算质量好坏的“方差比ratio”指标值均第二章 控制点复测成果表江西省交通工程集团公司高速公路A7标主线GPS控制点复测坐标成果序号点 名设 计所在位置备 注X（m）Y（m）1GD45-12748885.140 479493.313 盘龙山高架桥加密导线点2GD45-22748753.074 479350.190 3G
