1、掌握GPS接收機采集的數(shù)據(jù)下載工具和使用；

2、掌握TGO軟件進行基線解算和閉合環(huán)路的檢驗。二、實驗軟件

GPS后處理軟件：HDS2003軟件

三、實驗內(nèi)容：用中海達軟件完成GPS靜態(tài)處理，包括基線結算，網(wǎng)平差等過程，實驗步驟數(shù)據(jù)導入，2.基線解算：（1）基線解算設置數(shù)據(jù)采樣間隔、截止高度角、大氣改正模型、模糊度解算方法、參考衛(wèi)星、采用的數(shù)據(jù)（歷元）、觀測值（單頻、雙頻）（2）基線解算將為通過基線重新基線結算設置，并進行結算直到全部基線通過結算。點擊搜索基線閉合差使同步環(huán)和異步環(huán)都合適。由于部分數(shù)據(jù)質(zhì)量的原因可能導致基線解算失敗，可通過查看基線解算后衛(wèi)星觀測值的殘差來判斷質(zhì)量較差的數(shù)據(jù)，可以通過更改基線解算的設置來處理，如果更改設置后個別基線仍不成功，則應該刪除掉基線報告基線簡表L1&L2X增量Y增量Z增量距離三差解0.0049180.76271.525058.9447190.1367雙差解0.0044180.75511.515758.9397190.1279整數(shù)解0.0045180.75781.515958.9407190.1307L1&L2X增量Y增量Z增量距離三差解0.0137177.2172-0.877257.7420186.3890雙差解0.0059180.75331.519758.9346190.1246整數(shù)解0.0062180.75671.521458.9366190.1284L1&L2X增量Y增量Z增量距離三差解0.0052-26.1632-69.082982.6062110.8185雙差解0.0043-26.1650-69.076182.6016110.8113整數(shù)解0.0047-26.1952-69.090882.5980110.8249L1&L2X增量Y增量Z增量距離三差解0.0165-28.8405-72.218581.7228112.8092雙差解0.0063-26.1882-69.086782.6003110.8224整數(shù)解0.0064-26.1932-69.089582.6009110.8258L1&L2X增量Y增量Z增量距離三差解0.0074160.3059-67.1209144.1974225.8231雙差解0.0061159.1547-67.9895143.7551224.9851整數(shù)解0.0075159.1227-67.9976143.7552224.9650L1&L2X增量Y增量Z增量距離三差解0.0069157.8625-68.8055143.5244224.1741雙差解0.0051159.1430-67.9893143.7580224.9787整數(shù)解0.0055159.1246-67.9929143.7573224.9663L1&L2X增量Y增量Z增量距離三差解0.0085340.1485-65.9634203.3658401.7584雙差解0.0056337.7328-67.3678202.6218399.5716整數(shù)解0.0077337.7874-67.3501202.6295399.6187L1&L2X增量Y增量Z增量距離三差解0.0072337.1237-68.2152202.5008399.1394雙差解0.0057337.7718-67.3465202.6263399.6033整數(shù)解0.0064337.7901-67.3458202.6292399.6201L1&L2X增量Y增量Z增量距離三差解0.0052358.02275.7990112.3443375.2801雙差解0.0058357.99685.7833112.3432375.2548整數(shù)解0.0075357.98495.7771112.3417375.2429L1&L2X增量Y增量Z增量距離三差解0.0071357.98135.7634112.3127375.2305雙差解0.0062358.00595.7800112.3311375.2598整數(shù)解0.0080357.99045.7743112.3303375.2447L1&L2X增量Y增量Z增量距離三差解0.0064-207.3641-71.178323.3925220.4846雙差解0.0058-206.9496-70.604023.6607219.9384整數(shù)解0.0060-206.9529-70.606123.6588219.9420L1&L2X增量Y增量Z增量距離三差解0.0063-206.7459-70.668823.5058219.7509雙差解0.0060-206.9703-70.615823.6597219.9616整數(shù)解0.0076-206.9505-70.610723.6616219.9415L1&L2X增量Y增量Z增量距離三差解0.0071-21.7049-69.804884.6610111.8539雙差解0.0070-21.5853-69.501984.8200111.7626整數(shù)解0.0078-21.6353-69.512184.8159111.7754L1&L2X增量Y增量Z增量距離三差解0.0051-21.6662-69.532984.8173111.7954雙差解0.0049-21.6370-69.519884.8189111.7828整數(shù)解0.0057-21.6324-69.516784.8197111.7806L1&L2X增量Y增量Z增量距離三差解0.0052157.2500-68.7932143.7296223.8711雙差解0.0058157.0812-68.8420143.6992223.7480整數(shù)解0.0072157.0288-68.8654143.6885223.7116L1&L2X增量Y增量Z增量距離三差解0.0085159.7767-68.2484143.9955225.6571雙差解0.0066157.0072-68.8743143.6904223.7004整數(shù)解0.0069157.0329-68.8701143.6898223.7168L1&L2X增量Y增量Z增量距離三差解0.0060177.23194.265853.3981185.1504雙差解0.0062177.23134.264453.4029185.1513整數(shù)解0.0075177.22854.261153.4010185.1480L1&L2X增量Y增量Z增量距離三差解0.0061177.49594.240053.2712185.3661雙差解0.0057177.22264.247753.3927185.1396整數(shù)解0.0074177.23604.250753.3948185.1531L1&L2X增量Y增量Z增量距離三差解0.0138185.29550.912861.0596195.0988雙差解0.0074185.37031.110761.1621195.2029整數(shù)解0.0081185.31741.096561.1594195.1518L1&L2X增量Y增量Z增量距離三差解0.0077185.47120.875160.8880195.2119雙差解0.0075185.37141.113761.1714195.2069整數(shù)解0.0085185.31731.096761.1596195.1518L1&L2X增量Y增量Z增量距離三差解0.0084360.88910.6774119.5372380.1718雙差解0.0060363.99401.7440120.0299383.2778整數(shù)解0.0067363.98221.7376120.0285383.2661L1&L2X增量Y增量Z增量距離三差解0.0070365.45272.0451120.1273384.6952雙差解0.0064363.98971.7490120.0286383.2733整數(shù)解0.0067363.98321.7447120.0294383.2673L1&L2X增量Y增量Z增量距離三差解0.0061384.131274.875029.7574392.4902雙差解0.0068384.175474.869029.7444392.5314整數(shù)解0.0078384.180274.867629.7409392.5355L1&L2X增量Y增量Z增量距離三差解0.0049384.173474.876529.7342392.5300雙差解0.0048384.174374.858229.7327392.5273整數(shù)解0.0050384.184374.863529.7324392.5381L1&L2X增量Y增量Z增量距離三差解0.0081176.1441-0.157858.4862185.6002雙差解0.0064178.64510.643358.8726188.0969整數(shù)解0.0072178.66600.643358.8714188.1165L1&L2X增量Y增量Z增量距離三差解0.0094179.55610.787559.6540189.2078雙差解0.0059178.65190.647158.8728188.1035整數(shù)解0.007020.202173.1190-90.2968117.9323平差報告§1.1項目屬性項目名稱:項目單位:施工單位:負責人:控制網(wǎng)等級:D測量員:計算員開始日期:結束日期:備注:§1.2坐標系統(tǒng)坐標系名稱:
