GPS与数字化测图技术总结学院：测绘地理信息学院班级：测绘工程10-2 班姓名：*二一三年七月八日 GPS数据处理技术总结一、 测区概况本次实习测区主要集中在*大学（*校区）与*大学（*校区）周边。测区范围内山区较多，道路复杂，房屋众多。原有已知E级网点遭到损坏，测区内通视情况欠佳。布点位置相对地域开阔，便于进行GPS观测。测区内平均高程为海拔150米。测区控制范围大致位于东经11016 02 - 11019 05，北纬2503 10 - 2506 56 之间。二、 作业依据和已有测绘资料1、GPS与数字化测图实习指导书；2、技术设计书；3. 全球定位系统城市测量技术规程 CJJ 73-1997；4. 全球定位系统（GPS）测量规范(GB/T 18314-2001) 。 城市各级GPS控制网平均边长

（10mm+2ppmD）这些GPS测量系统配备有星历预报软件、后处理解算软件，完全能满足GPS控制测量数据处理的要求。南方数据转换软件为南方GPS后处理程序，基线结算及平差软件为中海达HGO数据处理软件，能够基线向量处理、GPS网平差软件、多种GPS数据格式转换等功能，完全能满足GPS控制测量数据处理的要求。 GPS实测和数据处理时采用的其它设备移动电话、对讲机、计算机和必要的交通工具等。六、E级GPS网的设计和观测 1GPS布网充分利用GPS测量的优点，实测GPS控制点15个，其中已知点10个（采用5个平差），未知点5个，可使用接收机7台，分七个小组进行测量。网的设计是采用网连式布网方式，每1期都保持2台不变另外五台流动的方式。控制网如图所示： （GPS网型图）2.GPS观测 在实际外业观测过程中，使用7台GPS接收机同时在不同的7个点上进行观测，观测四个时段，时段长度为大于90 min。 丈量天线高度, 均从天线的三面丈量三次, 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。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,否则及时通知其它仪器, 延长时段时间, 以保证观测精度。 实际上在观测过程中，GPS接收机电量充足，接收信号稳定，为后面的平差处理之顺利进行打下了良好的基础。七.内业数据处理步骤1. 数据记录情况通过对记录数据的检查，包括GPS测量数据和设站记录表，都没发现什么大问题，内业处理所需数据符合数据处理要求。2. 内业处理准备工作整个项目的数据已经准备就绪，接下来是准备相关软件的启用，该项目所必需软件为：南方测绘 GPS数据处理和中海达HGO数据处理软件。3.内业的处理软件的使用我们的观测数据为南方GPS STH格式数据，数据的主要处理在HGO软件上完成，因此需要将南方的STH格式数据转换成标准的RINEX格式数据。将所有南方STH数据导入到南方测绘 Gps数据处理软件，输入量取天线高和选择量取部位后，天线高的量取位置均为测高片，最后全部数据按RINEX格式成果输出。其次，将标准格式数据导入HGO并进行基线处理。再处理过程中，只有部分基线不合格。认为观测质量良好。在数据导入过程中，为了提高工作效率，我采用分期导入的方法。修改基线我主要采用修改卫星残差图的方法进行。卫星高度截止角全部为，采样间隔，最小历元数。通过观察，禁用观测时常过短、周跳频繁而且超限的卫星信号。禁用部分卫星观测信号的不好的部分。把所有的基线的粗差处理完之后，进行GPS基线处理。处理完毕之后，打开不合格基线的处理报告，并根据报告中的卫星信号情况对相应的基线进行修改。在所有的基线处理合格之后，把整个数据库的闭合环报告打开，查看是否有失败的闭合环，如果有失败的闭合环，那么根据闭合环报告进行相应的基线处理；如果有同时有个以上同步环因为某条基线而导致同时不合格，那么首先处理这条基线。本次处理中，发现第一期数据的周跳频繁，故在允许的范围内禁用部分基线，直到数据合格。基线共有156条，禁用13条。禁用基线总基线10%，符合标准。最后进行平差，导出相应的报告。八、平差处理结果和报告（附）注：平差处理结果和报告截取于中海达HGO软件处理数据结束导出的项目报告。附
