內(nèi)置收發(fā)一體電臺，基準站與移動站能完全互換距離外掛電臺隨心選配

智能化的故障自我診斷功能

更大的電池容量，單電池達到5000mAh清，周珊珊，張曉雅)協(xié)助指導教師負責組織本小組的各項實習、儀器的借用與保管、全部實習由指導教師統(tǒng)一指揮，班干部及各組組長應積極配合教師做好本班、本三、測區(qū)概況南京信息工程大學坐落于古城南京浦口區(qū)，整個測區(qū)位于北緯32°12′到北緯測前(1)點之記的制作況(見附錄)。(2)網(wǎng)型設計型設計草圖如圖所示(圖1)測量順序按照如圖的(1)——(2)——(3)——(4)測中組內(nèi)一人負責儀器開關及操縱，另外兩人負責測量儀器高、表格記錄、組組之間聯(lián)絡等任務。儀器在測量時間至少確保有一個人在照看儀器。每組之間提前確定好開關機時間，統(tǒng)一開關機，讓儀器實現(xiàn)同步聯(lián)測，并且各組之間保持聯(lián)絡隨時通報儀器情況，以免出現(xiàn)個別儀器出現(xiàn)問題或者弄錯時間等。測后(1)導出GPS機上的數(shù)據(jù)，并對數(shù)據(jù)進行初步處理：②對個數(shù)據(jù)文件輸入儀器高(GPS機每次開關機進行一次測量就生成一個數(shù)據(jù)文行入到HDS2003數(shù)據(jù)處理軟件中，并對坐標系統(tǒng)，天線管理，基線處理設置等進行設置，檢查網(wǎng)圖是否正確。④進行基線解算，并檢查是否有錯誤。⑤進行網(wǎng)評差，并查看網(wǎng)評差報告，檢查是否有錯誤。⑥導出網(wǎng)圖，網(wǎng)評差報告等處理結果。六、實習成果1項目屬性項目名稱:項目單位:責任人:開始日期:結束日期:描述:1.1坐標系統(tǒng)坐標系名稱:橢球:橢球長半軸:橢球扁率倒數(shù):格網(wǎng)文件:投影方法:中央經(jīng)線:中央緯度:原始緯度:比例系數(shù):m:第一緯度:第二緯度:S2010級測繪工程6月十五號default163782453Guass3114:00:00.00000E000:00:00.00000N000:00:00.00000N10000:00:00.00000N000:00:00.00000N00001.2解算數(shù)據(jù)觀測文件總數(shù):15站點個數(shù):9形成基線總條數(shù):15形成重復條數(shù):1形成同步環(huán)個數(shù):5形成異步環(huán)個數(shù):2合格:1合格:1合格:2不合格:0不合格:02觀測文件觀測文件_5481650.GNS_5481651.GNS_5481652.GNS_5481653.GNS_5481660.GNS采樣間隔)55555開始時2013/6/142013/6/14:102013/6/14:102013/6/142013/6/15結束時2013/6/142013/6/142013/6/14:252013/6/1420:10:502013/6/15觀測時長01:02:2501:08:5500:58:1501:06:1001:05:55站點名NG04NG04NG08NG09NG03線高(m)0.04900.04900.04900.04900.0490接收機20015482001548200154820015482001548:30:25_5981650.GN52013/6/12013/6/101:02:1NG00.049200159S440208_5981651.GN52013/6/12013/6/101:12:1NG00.049200159S4:2045608_5981652.GN52013/6/12013/6/100:58:2NG00.049200159S4:154:405608_5981653.GN52013/6/12013/6/100:58:3NG00.049200159S4420:5:505708_5981660.GN52013/6/12013/6/101:03:2NG00.049200159S5:255:450708_6671651.GN52013/6/12013/6/101:03:4NG00.049200166S445107_6671652.GN52013/6/12013/6/101:09:0NG00.049200166S445107平平面精:55_6671653.GN52013/6/12013/6/101:26:0NG10.049200166S4:1045007_6671654.GN52013/6/12013/6/100:59:2NG10.049200166S4420:7:300007_6671660.GN52013/6/12013/6/101:05:3NG00.049200166S55:3554073基線解算3.1基線成果RaRatDX(m)DY(m)DZ(m)_5981650.zsd-_6671651.zsd度RMS(mm)度高程精度長_5481660.zsd-_6671Rat660.zsdio-258.2-258.2-258.2DX(m)-366.034.482034.460534.4829DY(m)-83.70-230.4-230.52-230.401DZ(m)-156.9m)347.84347.84347.83481.0平面精度長度RMS(m高(m)m)程精度m)406.996.9-366.2-366.0_5481660.zsd-_5981RatDX(m)660.zsdio-852.0-852.0-83.74-83.74DY(m)-675.3-675.3-156.90-156.93DZ(m)283.64283.61407.14407.014572.2平面精度長度RMS(m高(m)m)程精度m)04.9-851.945_5481650.zsd-_6671RatDX(m)651.zsdio11-675.3DY(m)298.16298.20298.24283.61DZ(m)-319.9-319.9-319.95711.7平面精度長度RMS(m高(m)m)程精度m)452.884452.89452.898.37_5481651.zsd-_6671652.zsd_5481650.zsd-_5981650.zsdRatDX(m)RatDX(m)DY(m)298.25298.28298.27DY(m)DZ(m)-319.96-319.95-319.9DZ(m)長度452.86452.91452.90長度RMS(mm).2RMS(mm)9平面精度高程精度m)02平面高375.75375.70375.72_5481651.zsd-_5981RatDX(m)651.zsdio263.78263.75263.77DY(m)-89.40-89.43-89.43DZ(m)467.72467.67467.70長度精度高程精度m)8.070平面RMS(mm)度度度高程精度-446.0-445.913-446.0_5981651.zsd-_6671RatDX(m)652.zsdio-362.75-362.6-362.65DY(m)DZ(m)597.02596.94596.98長度程精度m)89平面精RMS(mm)_5981652.zsd-_6671Rat653.zsdio563.54563.52563.53DX(m)-597.6660.90660.92660.93DY(m)-443.6-480.9-480.9-480.9DZ(m)m)992.80992.80992.82070.9平面精度長度RMS(m高(m)m)程精度m)761.877.3-597.70-597.6_5981660.zsd-_6671RatDX(m)660.zsdio485.94485.873-443.66-443.6DY(m)591.59591.58DZ(m)-440.569-440.579761.92.25761.875.2760.6平面精度長度RMS(m高(m)m)程精度m)883.31883.26.4485.91_5981653.zsd-_6671RatDX(m)654.zsdio-557.739-557.7-557.7410591.57DY(m)-214.9-214.7-214.784-440.509DZ(m)-117.03-116.99-116.988883.28761.2平面精度長度RMS(m高(m)m)程精度m)609.11.3609.03609.0016.61_5481652.zsd-_5981652.zsd_5481652.zsd-_6671653.zsdRatDX(m)336.20336.23336.18RatDX(m)DY(m)202.73202.80202.79DY(m)DZ(m)-18.22-18.17-18.18DZ(m)長度393.02393.08393.03長度RMS(mm)8.0.9RMS(mm)9平面精度高程精度m)66平面高-261.4-261.4-261.46_5481653.zsd-_5981RatDX(m)653.zsdio-240.8-240.8-240.8448DY(m)DZ(m)383.68383.72383.71長度精度高程精度m)5.15平面RMS(mm)度度度高程精度367.82367.72367.71_5481653.zsd-_6671RatDX(m)654.zsdioDY(m)DZ(m)402.18402.00401.97長度程精度m).248平面精RMS(mm)--190.0-190.0448-190.0m).579-95.71-95.56-95.57-6.7604-6.6815-6.6945212.88212.82212.813.2重復基線檢查名名稱X質量檢查mm)Rat基線Ymm)RMSdZ(mm)DX(m)長度較差DY(m)長度平均較差邊長長度DZ(m)NG01-NG04(最合格_5481650.zsd-_6110.9298.452.95-319.28.3452.誤差環(huán)環(huán)總671651.zsd0835083243993398966_5481651.zsd-_60.0117.298.-319.452.671652.zsd151510727922790653.3同步環(huán)檢查名稱NG01-NG02-NG04-1(最質量檢查基線不合格_5981650.zsd-_6671651.zsdWX(mm)RatWY(WZ(mmm)m)RMSDX(m.830.0-258WS(mm)DY(m).429長DZ(m)-2307.8348長總相限對差精度m)pm)5_5481650.zsd-_6671651.zsd_5481650.zsd-_5981650.zsdNG03-NG04-不合格NG07-1_5481660.zsd-_6671660.zsd_5481660.zsd-_5981660.zsd_5981660.zsd-_6671660.zsdNG01-NG04-不合格NG06-1_5481651.zsd-_6671652.zsd17-3.6290304.3014.307835.41-3669-8515485.914207298.2439263..3-83.-67511.5298.1-3199-89.4342413-156383.6175-44092042-319452.8966467.10407.01571883.28760452.9065_5481651.zsd-_5981651.zsd_5981651.zsd-_6671652.zsdNG06-NG08-合格NG10-1_5981652.zsd-_6671653.zsd_5481652.zsd-_5981652.zsd_5481652.zsd-_6671653.zsdNG07-NG09-不合格NG10-1_5981653.zsd-_6671654.zsd4.43900-1.50209010-44693.68-0.6-
