【摘要】：當前，網(wǎng)絡RTK技術已成為測繪領域的研究熱點之一。但，該技術在我國工程建設領域尚未普及。并且，幾乎很少對網(wǎng)絡RTK的技術構建和應用方面進行系統(tǒng)地分析對比。故而本文認為有必要對其進行研究。 文章在介紹網(wǎng)絡RTK技術原理的基礎上，主要對單基站網(wǎng)絡RTK、移動基站式網(wǎng)絡RTK和多基站網(wǎng)絡RTK的基準站建設和技術構建流程做了詳細的研究，并對比分析各自的優(yōu)缺點，總結出對工程建設具有參考價值的建議。 最后，通過具體實驗研究了坐標轉換參數(shù)對測量精度的影響，，包括已知點含有微小誤差對測量精度的影響、控制網(wǎng)的大小不同對測量精度的影響兩部分內容。然后，又比較分析了三種形式的網(wǎng)絡RTK測量精度與距基準站距離的關系，在10km、20km、35km范圍內對所選的測試點進行實時動態(tài)測量，并對測試數(shù)據(jù)的測量精度進行分析比較。得出三種形式的網(wǎng)絡RTK在什么樣的范圍內保證5cm的測量精度。提出具有一定實際應用價值的建議。
[Abstract]:At present, network RTK technology has become one of the research hotspots in the field of surveying and mapping. However, the technology has not been popularized in the field of engineering construction in China. Moreover, few systematic analysis and comparison are made on the technical construction and application of network RTK. Therefore, it is necessary to study it in this paper. On the basis of introducing the technical principle of network RTK, this paper makes a detailed study on the base station construction and technical construction flow of single base station network, mobile base station network RTK and multi-base station network RTK, and compares and analyzes their advantages and disadvantages. The suggestions of reference value for engineering construction are summarized. Finally, the influence of coordinate conversion parameters on measurement accuracy is studied through experiments, including the influence of small errors in known points on measurement accuracy, and the influence of different control network size on measurement accuracy. Then, the relationship between the measurement accuracy of three kinds of network RTK and the distance from the reference station is compared and analyzed. The real-time dynamic measurement of the selected test points is carried out in the range of 10 km / 20 km2 / 35km, and the measurement accuracy of the test data is analyzed and compared. The range of three types of network RTK to ensure the measurement accuracy of 5cm is obtained. Some suggestions with practical application value are put forward.
