GPS基线处理要点(共11页).doc

精选优质文档-倾情为你奉上GPS测量数据处理一、实验目的      1、掌握GPS接收机采集的数据下载工具和使用；      2、掌握TGO软件进行基线解算和闭合环路的检验。二、实验软件       GPS后处理软件：HDS2003软件 三、实验内容：用中海达软件完成GPS静态处理，包括基线结算，网平差等过程， 五、 实验步骤1. 数据导入， 2.基线解算：（1）基线解算设置 数据采样间隔、截止高度角、大气改正模型、模糊度解算方法、参考卫星、采用的数据（历元）、观测值（单频、双频）（2） 基线解算 将为通过基线重新基线结算设置 ，并进行结算直到全部基线通过结算。 点击搜索基线闭合差使同步环和异步环都合适。由于部分数据质量的原因可能导致基线解算失败，可通过查看基线解算后卫星观测值的残差来判断质量较差的数据，可以通过更改基线解算的设置来处理，如果更改设置后个别基线仍不成功，则应该删除掉 基线报告 基线简表L1 & L2X 增量Y 增量Z 增量距离三差解0.0049180.76271.525058.9447190.1367双差解0.0044180.75511.515758.9397190.1279整数解0.0045180.75781.515958.9407190.1307L1 & L2X 增量Y 增量Z 增量距离三差解0.0137177.2172-0.877257.7420186.3890双差解0.0059180.75331.519758.9346190.1246整数解0.0062180.75671.521458.9366190.1284L1 & L2X 增量Y 增量Z 增量距离三差解0.0052-26.1632-69.082982.6062110.8185双差解0.0043-26.1650-69.076182.6016110.8113整数解0.0047-26.1952-69.090882.5980110.8249L1 & L2X 增量Y 增量Z 增量距离三差解0.0165-28.8405-72.218581.7228112.8092双差解0.0063-26.1882-69.086782.6003110.8224整数解0.0064-26.1932-69.089582.6009110.8258L1 & L2X 增量Y 增量Z 增量距离三差解0.0074160.3059-67.1209144.1974225.8231双差解0.0061159.1547-67.9895143.7551224.9851整数解0.0075159.1227-67.9976143.7552224.9650L1 & L2X 增量Y 增量Z 增量距离三差解0.0069157.8625-68.8055143.5244224.1741双差解0.0051159.1430-67.9893143.7580224.9787整数解0.0055159.1246-67.9929143.7573224.9663L1 & L2X 增量Y 增量Z 增量距离三差解0.0085340.1485-65.9634203.3658401.7584双差解0.0056337.7328-67.3678202.6218399.5716整数解0.0077337.7874-67.3501202.6295399.6187L1 & L2X 增量Y 增量Z 增量距离三差解0.0072337.1237-68.2152202.5008399.1394双差解0.0057337.7718-67.3465202.6263399.6033整数解0.0064337.7901-67.3458202.6292399.6201L1 & L2X 增量Y 增量Z 增量距离三差解0.0052358.02275.7990112.3443375.2801双差解0.0058357.99685.7833112.3432375.2548整数解0.0075357.98495.7771112.3417375.2429L1 & L2X 增量Y 增量Z 增量距离三差解0.0071357.98135.7634112.3127375.2305双差解0.0062358.00595.7800112.3311375.2598整数解0.0080357.99045.7743112.3303375.2447L1 & L2X 增量Y 增量Z 增量距离三差解0.0064-207.3641-71.178323.3925220.4846双差解0.0058-206.9496-70.604023.6607219.9384整数解0.0060-206.9529-70.606123.6588219.9420L1 & L2X 增量Y 增量Z 增量距离三差解0.0063-206.7459-70.668823.5058219.7509双差解0.0060-206.9703-70.615823.6597219.9616整数解0.0076-206.9505-70.610723.6616219.9415L1 & L2X 增量Y 增量Z 增量距离三差解0.0071-21.7049-69.804884.6610111.8539双差解0.0070-21.5853-69.501984.8200111.7626整数解0.0078-21.6353-69.512184.8159111.7754L1 & L2X 增量Y 增量Z 增量距离三差解0.0051-21.6662-69.532984.8173111.7954双差解0.0049-21.6370-69.519884.8189111.7828整数解0.0057-21.6324-69.516784.8197111.7806L1 & L2X 增量Y 增量Z 增量距离三差解0.0052157.2500-68.7932143.7296223.8711双差解0.0058157.0812-68.8420143.6992223.7480整数解0.0072157.0288-68.8654143.6885223.7116L1 & L2X 增量Y 增量Z 增量距离三差解0.0085159.7767-68.2484143.9955225.6571双差解0.0066157.0072-68.8743143.6904223.7004整数解0.0069157.0329-68.8701143.6898223.7168L1 & L2X 增量Y 增量Z 增量距离三差解0.0060177.23194.265853.3981185.1504双差解0.0062177.23134.264453.4029185.1513整数解0.0075177.22854.261153.4010185.1480L1 & L2X 增量Y 增量Z 增量距离三差解0.0061177.49594.240053.2712185.3661双差解0.0057177.22264.247753.3927185.1396整数解0.0074177.23604.250753.3948185.1531L1 & L2X 增量Y 增量Z 增量距离三差解0.0138185.29550.912861.0596195.0988双差解0.0074185.37031.110761.1621195.2029整数解0.0081185.31741.096561.1594195.1518L1 & L2X 增量Y 增量Z 增量距离三差解0.0077185.47120.875160.8880195.2119双差解0.0075185.37141.113761.1714195.2069整数解0.0085185.31731.096761.1596195.1518L1 & L2X 增量Y 增量Z 增量距离三差解0.0084360.88910.6774119.5372380.1718双差解0.0060363.99401.7440120.0299383.2778整数解0.0067363.98221.7376120.0285383.2661L1 & L2X 增量Y 增量Z 增量距离三差解0.0070365.45272.0451120.1273384.6952双差解0.0064363.98971.7490120.0286383.2733整数解0.0067363.98321.7447120.0294383.2673L1 & L2X 增量Y 增量Z 增量距离三差解0.0061384.131274.875029.7574392.4902双差解0.0068384.175474.869029.7444392.5314整数解0.0078384.180274.867629.7409392.5355L1 & L2X 增量Y 增量Z 增量距离三差解0.0049384.173474.876529.7342392.5300双差解0.0048384.174374.858229.7327392.5273整数解0.0050384.184374.863529.7324392.5381L1 & L2X 增量Y 增量Z 增量距离三差解0.0081176.1441-0.157858.4862185.6002双差解0.0064178.64510.643358.8726188.0969整数解0.0072178.66600.643358.8714188.1165L1 & L2X 增量Y 增量Z 增量距离三差解0.0094179.55610.787559.6540189.2078双差解0.0059178.65190.647158.8728188.1035整数解0.007020.202173.1190-90.2968117.9323平差报告§1.1 项目属性项目名称:项目单位:施工单位:负责人: 控制网等级:D测量员: 计算员开始日期:结束日期:备注:§1.2 坐标系统坐标系名称: 椭球长半轴 a：. 椭球扁率 f：1/298. 投影名称:高斯投影 尺度:1. 投影高:0. X加常数:0.
