東華理工大學(xué)RTK實習(xí)報告

1、RTK實習(xí)報告姓名：鄧博陽 班級：1432001 專業(yè)：測繪工程 學(xué)號：201430200114一、 實習(xí)目的正確認(rèn)識和理解RTK定位技術(shù)，學(xué)會并掌握RTK在工程上的放樣過程。 RTK定位技術(shù)是基于載波相位觀測值的實時動態(tài)定位技術(shù)，它能夠?qū)崟r地提供測站點在指定坐標(biāo)系中的三維定位結(jié)果，并達到厘米級精度。在RTK作業(yè)模式下，基準(zhǔn)站通過數(shù)據(jù)鏈將其觀測值和測站坐標(biāo)信息一起傳送給流動站。流動站不僅通過數(shù)據(jù)鏈接收來自基準(zhǔn)站的數(shù)據(jù)，還要采集GPS觀測數(shù)據(jù)，并在系統(tǒng)內(nèi)組成差分觀測值進行實時處理。流動站可處于靜止?fàn)顟B(tài)，也可處于運動狀態(tài)。RTK技術(shù)的關(guān)鍵在于數(shù)據(jù)處理技術(shù)和數(shù)據(jù)傳輸技術(shù)。 RTK 系統(tǒng)正常工作要具備

2、以下三個條件：第一，基準(zhǔn)站和移動站同時接收到5顆以上GPS衛(wèi)星信號；第二，基準(zhǔn)站和移動站同時接收到衛(wèi)星信號和基準(zhǔn)站發(fā)出的差分信號；第三，基準(zhǔn)站和移動站要連續(xù)接收 GPS 衛(wèi)星信號和基準(zhǔn)站發(fā)出的差分信號。即移動站遷站過程中不能關(guān)機，不能失鎖。否則RTK須重新初始化。二、實習(xí)地點及時間1.地點：東華理工大學(xué)長江學(xué)院本部東華廣場和一教2.時間：2016年12月24日。三：實習(xí)任務(wù) 1、了解和掌握RTK的基本原理和作業(yè)模式。 2、利用RTK進行點的放樣。 3、了解RTK的優(yōu)點和局限性四、RTK的原理實時動態(tài)測量的基本思想是在基準(zhǔn)站上安置一臺GPS接收機，對所有可見GPS衛(wèi)星進行連續(xù)觀測，并將其觀測數(shù)據(jù)

3、，通過無線電傳輸設(shè)備，實時地發(fā)送給流動站。在流動站上，GPS接收機在接受GPS衛(wèi)星信號的同時，通過無線電接收設(shè)備，接受基準(zhǔn)站傳輸?shù)挠^測數(shù)據(jù)，然后根據(jù)相對定位的原理，實時地計算并顯示流動站的三維坐標(biāo)及精度。這樣，通過實時計算的定位結(jié)果，便可監(jiān)測基準(zhǔn)站與流動站觀測成果的質(zhì)量和解算結(jié)果的收斂情況，從而可實時地判定解算結(jié)果是否成功，以減少冗余觀測，縮短觀測時間。GPS定位的原理是GPS 衛(wèi)星發(fā)射的測距信號和導(dǎo)航電文導(dǎo)航電文中含有衛(wèi)星位置的信息用戶用GPS接收機在某一時刻接收三顆或三顆以上的GPS衛(wèi)星測出測站點(GPS天線中心)到衛(wèi)星的距離并解算出該時刻衛(wèi)星的空間位置根據(jù)距離并解算出衛(wèi)星的空間位置根據(jù)距

4、離交會法求測站點坐標(biāo)其基本思想為在基準(zhǔn)站上安置一臺GPS 接收機,對所有可見衛(wèi)星進行連續(xù)觀測并將其觀測數(shù)據(jù)通過無線電傳輸設(shè)備實時地發(fā)送給用戶觀測站,用戶站在接收GPS衛(wèi)星信號的同時,通過無線電接收機設(shè)備接收基準(zhǔn)站傳輸?shù)挠^測據(jù),實時計算測站點的三維坐標(biāo)。五、RTK 的作業(yè)過程 1）啟動基準(zhǔn)站。將基準(zhǔn)站架設(shè)在上空開闊、沒有強電磁干擾、多路徑誤差影響小的控制點上，正確連接好各儀器電纜，打開各儀器。將基準(zhǔn)站設(shè)置為動態(tài)測量模式。 2）建立新工程，定義坐標(biāo)系統(tǒng)新建一個工程，即新建一個文件夾，并在這個文件夾里設(shè)置好測量參數(shù)如橢球參數(shù)、投影參數(shù)等。這個文件夾中包括許多小文件，它們分別是測量的成果文件和各種參數(shù)

5、設(shè)置文件，如*.dat、*.cot、*.rtk、*.ini等。 3）點校正 CPS 測量的為 WCS -84 系坐標(biāo)，而我們通常需要的是在流動站上實時顯示國家坐標(biāo)系或地力獨立坐標(biāo)系下的坐標(biāo)，這需要進行坐標(biāo)系之間的轉(zhuǎn)換，即點校正。點校正可以通過兩種方式進行。A、在已知轉(zhuǎn)換參數(shù)的情況下。如果有當(dāng)?shù)刈鴺?biāo)系統(tǒng)與 WCS-84 坐標(biāo)系統(tǒng)的轉(zhuǎn)換七參數(shù)，則可以在測量控制器中直接輸入，建立坐標(biāo)轉(zhuǎn)換關(guān)系。如果上作是在國家大地坐標(biāo)系統(tǒng)下進行，而且知道橢球參數(shù)和投影方式以及基準(zhǔn)點坐標(biāo)，則可以直接定義坐標(biāo)系統(tǒng)，建議在 RTK 測量中最好加入 1-2 個點校正，避免投影變形過大，提高數(shù)據(jù)可靠性。B、在不知道轉(zhuǎn)換參數(shù)的情

6、況下。如果在局域坐標(biāo)系統(tǒng)中工作或任何坐標(biāo)系統(tǒng)進行測量和放樣工作，可以直接采用點校正方式建立坐標(biāo)轉(zhuǎn)換方式，平面至少 3 個點，如果進行高程擬合則至少要有 4 個水準(zhǔn)點參與點校正。 4）流動站開始測量A、單點測量：在主菜單上選擇“測量”圖標(biāo)打開，測量方式選擇“RTK”, 再選擇“測量點”選項，即可進行單點測量。注意要在“固定解”狀態(tài)下，才開始測量。單點測量觀測時間的長短與跟蹤的衛(wèi)星數(shù)量、衛(wèi)星圖形精度、觀測精度要求等有關(guān)。當(dāng)“存儲”功能鍵出現(xiàn)時，若滿足要求則按“存儲”鍵保存觀測值，否則按“取消”放棄觀測。 B、放樣測量：在進行放樣之前，根據(jù)需要“鍵入”放樣的點、直線、曲線、 DTM 道路等各項放樣數(shù)

7、據(jù)。當(dāng)初始化完成后，在主菜單上選擇“測量”圖標(biāo)打開，測量方式選擇“RTK”,再選擇“放樣”選項，即可進行放樣測量作業(yè)。在作業(yè)時，在手薄控制器上顯示箭頭及目前位置到放樣點的方位和水平距離，觀測值只需根據(jù)箭頭的指示放樣。當(dāng)流動站距離放樣點就距離小于設(shè)定值時，手薄上顯示同心圓和十字絲分別表示放樣點位置和天線中心位置。當(dāng)流動站天線整平后，十字絲與同心圓圓心重合時，這時可以按“測量”鍵對該放樣點進行實測，并保存觀測值。 3、利用RTK進行點放樣 1）測前準(zhǔn)備：獲取 23 個控制點的坐標(biāo)（如果沒有已知數(shù)據(jù)可用靜態(tài) GPS 先進行控制測量），解算或用相關(guān)軟件求出放樣點的坐標(biāo)，檢查儀器是否能正常使用。 2）站

8、的架設(shè)：將基準(zhǔn)站架設(shè)在較空曠的地方（附近無高大建筑物或高壓電線等）架設(shè)完后安裝電臺，連接好儀器后開啟基準(zhǔn)站主機，打開電臺并設(shè)置頻率。 3）建立新工程：開啟移動站主機，待衛(wèi)星信號穩(wěn)定并達到 5 顆以上衛(wèi)星時，先連接藍牙，連接成功后設(shè)置相關(guān)參數(shù)：工程名稱、橢球系名稱、投影參數(shù)設(shè)置、參數(shù)設(shè)置（未啟用可以不填寫），最后確定，工程新建完畢。 4）輸入放樣點：打開坐標(biāo)庫，在此我們可以輸入編輯放樣點，也可以事先編輯好放樣點文件，點擊打開放樣點文件，軟件會提示我們是對坐標(biāo)庫進行覆蓋或是追加。 5）測量校正：測量校正有兩種方法：控制點坐標(biāo)求校正參數(shù)和利用點校正。第一中方法,利用控制點坐標(biāo)庫(即計算校正參數(shù)的一個

9、工具)的做法大致是這樣的:假設(shè)我們利用 A,B 這兩個已知點來求校正參數(shù)，那么我們必須記錄下 A,B 這兩個點的原始坐標(biāo)(即移動站在 Fixed 的狀態(tài)下記錄的這兩個點的坐標(biāo))，先在控制點坐標(biāo)庫中輸入 A 點的已知坐標(biāo)之后軟件會提示你輸入 A 點的原始坐標(biāo)，然后再輸入 B 點的已知坐標(biāo)和 B 點的原始坐標(biāo)，這樣就計算出了校正參數(shù)。第二種方法，利用校正向?qū)Ｕ朔椒ㄓ址譃榛鶞?zhǔn)站在已知點校正和基準(zhǔn)站在未知點的校正。 我們這里只說明一下基準(zhǔn)站架設(shè)在未知點的校正方法。A、利用一點進行校正：步驟依次為工具-校正向?qū)?基準(zhǔn)站架設(shè)在未知點-輸入當(dāng)前移動站的已知坐標(biāo)-待移動站對中整平后并出現(xiàn)固定解-校正。B

10、、利用兩點校正：步驟依次為工具-校正向?qū)?基準(zhǔn)站架設(shè)在未知點-輸入當(dāng)前移動站的已知坐標(biāo)-待移動站對中整平后并出現(xiàn)固定解-下一步-將移動站移到下一個已知點-輸入當(dāng)前移動站的已知坐標(biāo)-待移動站對中整平后并出現(xiàn)固定解-校正。C、利用三點校正：與利用兩點校正相同，只是多增加了一個已知點，多重復(fù)了一遍。 6）放樣點：選擇測量-點放樣，進入放樣屏幕，點擊打開按鈕目，打開坐標(biāo)管理庫，在這里可以打開事先編輯好的放樣文件，選擇放樣點，也可以點擊“增加”輸入放樣點坐標(biāo)。 4、RTK 的技術(shù)特點 1）工作效率高：在一般的地形地勢下，高質(zhì)量的 RTK 設(shè)站一次即可測完 4km 半徑的測區(qū)，大大減少了傳統(tǒng)測量所需的控制

11、點數(shù)量和測量儀器的設(shè)站次數(shù)，移動站一人操作即可，勞動強度低，作業(yè)速度快，提高了工作效率。2）定位精度高：只要滿足 RTK 的基木工作條件，在一定的作業(yè)半徑范圍內(nèi)（一般為 4km ）RTK 的平而精度和高程精度都能達到厘米級。3）全天候作業(yè)：RTK 測量不要求基準(zhǔn)站、移動站間光學(xué)通視，只要求滿足 “電磁波通視”，因此和傳統(tǒng)測量相比，RTK 測量受通視條件、能見度、氣候、季節(jié)等因素的影響和限制較小，在傳統(tǒng)測量看來難于開展作業(yè)的地區(qū)，只要滿足 RTK 的基木工作條件，它也能進行快速的高精度定位，使測量工作變得史容易史輕松。 4）RTK 測量自動化、集成化程度高，數(shù)據(jù)處理能力強：RTK 可進行多種測量

12、內(nèi)、外業(yè)工作。移動站利用軟件控制系統(tǒng)，無需人工干預(yù)便可自動實現(xiàn)多種測繪功能，減少了輔助測量工作和人為誤差，保證了作業(yè)精度。 5）操作簡單、易于使用：現(xiàn)在的儀器一般都提供中文菜單，只要在設(shè)站時進行簡單的設(shè)置，就可方便地獲得二維坐標(biāo)。數(shù)據(jù)輸入、存儲、處理、轉(zhuǎn)換和輸出能力強，能方便地與計算機、其他測量儀器通信。 5、RTK的局限性和精度保障 RTK 也有其局限性，會影響到執(zhí)行上述測量任務(wù)的能力。了解其局限性可確保 RTK 測量成功。最主要的局限性其實不在于 RTK 本身，而是源于整個 GPS系統(tǒng)。如前所述，依靠的是接收兩萬多公里高空的衛(wèi)星發(fā)射來的無線電信號。 GPS相對而言，這些信號頻率高、信號弱，

13、不易穿透可能阻擋衛(wèi)星和 GPS接收機之間視線的障礙物。事實上，存在于 GPS接收機和衛(wèi)星之間路徑上的任何物體都會對系統(tǒng)的操作產(chǎn)生不良影響。有些物體如房屋，會完全屏蔽衛(wèi)星信號。因此,GPS不能在室內(nèi)使用。同樣原因, GPS也不能在隧道內(nèi)或水下使用。有些物體如樹木會部分阻擋、反射或折射信號。GPS信號的接收在樹林茂密的地區(qū)會很差。樹林中有時會有足夠的信號來計算概略位置，但信號清晰度難以達到厘米水平的精確定位。因此，RTK 在林區(qū)作業(yè)有一定的局限性。這并不是說，GPS RTK只適用于四周對空開闊的地區(qū)。RTK測量在部分障礙的地區(qū)也可以是有效而精確的。其奧秘是能觀測到足夠的衛(wèi)星來精確可靠地實現(xiàn)定位。在

14、任何時間、任何地區(qū)，都可能會有 7 到 10 顆 GPS 衛(wèi)星可用于 RTK 測量。RTK系統(tǒng)的工作并不需要這么多顆衛(wèi)星。如果天空中有 5 顆適當(dāng)分布的衛(wèi)星，就可作精確可靠的定位。有部分障礙的地點只要可以觀測到至少5顆衛(wèi)星，就有可能做 RTK 測量。在樹林或大樓四周作測量時，只要該地留有足夠的開放空間，使 RTK系統(tǒng)可觀測到至少5顆衛(wèi)星， RTK測量就有成功的條件。在論述 RTK技術(shù)的原理時，我們知道,RTK測量的關(guān)鍵是確定整周未知數(shù)，能否連續(xù)地、可靠地接收基準(zhǔn)站播發(fā)的信號，是RTK 能否成功的決定因素。在實際應(yīng)用中，來自各方面的干擾，降低了RTK 的可靠性和精度。 研究表明，為了保證地物點的

15、測量精度，我們在選點時要采取以下措施: 1、點位應(yīng)設(shè)在易于安裝接收機設(shè)備、視野開闊、視場內(nèi)周圍障礙物高度角應(yīng)小于 15°(如可以選在最高建筑物的頂樓)。 2、點位應(yīng)遠離大功率無線電發(fā)射源(如電視臺、微波站、微波通道等)，其距離不小于200 m；遠離高壓電線，距離不小于50m 。 3、點位附近不應(yīng)有大面積的水域或強烈干擾衛(wèi)星信號接收的物體。 4、點位選擇要充分考慮到與其它測量手段聯(lián)測和擴展。 5、點位要選在交通方便的地方，以提高工作效率。 6、點位要選在地面地基堅硬的地方，易于點的保存。除此之外，為了保證地物點的測量精度，我們還要對接收機天線進行校驗，選擇有削弱多路徑誤差的各種技術(shù)的天

16、線。同時，我們還要不斷利用新的數(shù)據(jù)處理技術(shù)，以削弱各種誤差帶來的影響。六、數(shù)據(jù) 001,00000000,435641.520,3097626.893,37.943002,00000000,435646.193,3097631.160,37.958003,00000000,435646.191,3097631.172,37.945004,00000000,435645.191,3097632.087,37.860005,00000000,435636.192,3097630.751,37.885006,00000000,435636.146,3097631.797,37.889007,0000
