style="text-indent:25px">GPS是全球定位系統(tǒng)的簡稱，是美國研制的一套衛(wèi)星導(dǎo)航系統(tǒng)。GPS衛(wèi)星可以向地面廣播的GPS導(dǎo)航定位信號，在美國軍方開放民用頻段后，其成為一種可供無數(shù)用戶分享的信息資源。GPS接收機能對GPS衛(wèi)星進行觀測及追蹤，在成功捕獲衛(wèi)星后GPS接收機就能接收不同衛(wèi)星的GPS導(dǎo)航信號并進行定位解算，用戶只需要要擁有GPS接收機及有關(guān)配套產(chǎn)品就能夠滿足地面、海面和太空空間的廣大的定位需求。隨著航空航天技術(shù)、遙感測繪技術(shù)的發(fā)展及經(jīng)濟全球化的世界貿(mào)易需求，新形勢下的定位技術(shù)要求：（1）提供精確的地心坐標(biāo)(衛(wèi)星和彈道導(dǎo)彈)；（2）提供全球統(tǒng)一的坐標(biāo)；（3）適應(yīng)長距離高精度定位；（4）全天候、快速精確、操作簡便。</p><p style="text-indent:25px">在具體的水利工程施工中，需要在落差較大、流量較小的地方設(shè)置引水式電站，首先需要建設(shè)施工控制網(wǎng)，以確保能夠順利貫徹引水隧洞。另外，還需要將水庫中水傳輸大發(fā)電站儲水庫中去，從而實現(xiàn)水能發(fā)電。因此，在水工隧洞貫通施工中，運用GPS技術(shù)，可以進一步簡化測量工序，利用GPS技術(shù)進行精細(xì)定位，以保證水工隧洞的順利貫通，不僅節(jié)約了時間，提高了效率，還**推進了整個水利工程測量工作的進度，為促進水利建設(shè)的可持續(xù)發(fā)展夯實基礎(chǔ)衛(wèi)星接收器的優(yōu)點和缺點。</p><p

style="text-indent:25px">可以同時接收12顆衛(wèi)星。早期的型號，比如GARMIN45C就是8通道。GPS接收機收到3顆衛(wèi)星的信號可以輸出2D（就是2維）數(shù)據(jù)，只有經(jīng)緯度，沒有高度，如果收到4顆以上的衛(wèi)星，就輸出3D數(shù)據(jù)，可以提供海拔高度。但是因為地球自己的問題，不是太標(biāo)準(zhǔn)的圓，所以高度數(shù)據(jù)有一些誤差?，F(xiàn)有些GPS接收機內(nèi)置了氣壓表，比如etrex的SUMMIT和VISTA，這些機器根據(jù)兩個渠道得到的高度數(shù)據(jù)綜合出終的海拔高度，應(yīng)該比較準(zhǔn)確了。GPS接收機的次開機，或者開機距離里上次關(guān)機地點超過800KM以上，因為接收機里存儲的星歷都對不上了，所以要在接收機上重新定位。GPS接收機的使用要在開闊的可見天空下，所以，屋里就不能用了。手持GPS的精度一般是誤差在10米左右，就是說一條路能看出走左邊還是右邊。精度主要依賴于衛(wèi)星的信號接收，和可接收信號的衛(wèi)星在天空的分布情況，如果幾顆衛(wèi)星分布的比較分散，GPS接收機提供的定位精度就會比較高。衛(wèi)星接收器降低了測量人員的工作強度。江西變形監(jiān)測衛(wèi)星接收器概念</p><p
