摘要:
基于信标互测距信息与绝对坐标信息的融合, 提出一种海洋大地控制网快速标校方法。相较于现有方法, 快速标校方法降低了自由网平差对起算条件的需求, 减少了50%以上的绝对标定点数目, 标校效率与绝对坐标精度显著提升。在大范围布设时, 优势明显。此外, 通过对阵型与绝对校准点数目的分析, 提出了几种典型阵型在理想条件下的布设方案。浅水试验结果表明, 在保证基准网标校精度高于0.2 m的条件下, 标校效率提升了50%。
Abstract:A rapid calibration method for marine geodetic control networks based on the combination of beacon mutual ranging information and absolute coordinate information is proposed. Compared with existing methods, the rapid calibration method reduces the initial condition restriction of free net adjustment; the number of absolute calibration points is reduced by more than 50%, and the calibration efficiency and absolute coordinate precision are significantly improved. In addition, several typical formations under ideal conditions are proposed by analyzing the formations and absolute calibration points. The shallow water test results show that the calibration efficiency is improved by 50% when the calibration precision of the reference network is greater than 0.2 m and the calibration precision of the reference network is greater than 0.2 m.
