摘要/Abstract

摘要： 利用泊松积分法和点质量法对澳大利亚West Arnhem Land区域的航空重力测量数据进行了精度评估,两种方法得到精度结果基本一致,评估结果表明GT-1A测量系统 2'分辨率数据的测量精度优于3×10^-5 m/s²,5'分辨率数据的测量精度优于2×10^-5 m/s².利用交叉点平差和泊松积分法、点质量法对渤海区域的航空重力测量进行了内部交叉点平差和外部精度评估,结果表明,内部评估精度与外部评估精度存在一定的差异,以外部评估为准则,CHAGS测量系统在渤海区域5'分辨率的航空重力数据精度优于3.5×10^-5 m/s².综合国内外试验情况分析得到,在近海区域,航空重力数据的分辨率和精度受测量仪器的性能而不同,整体上对于5'分辨率数据而言,可以达到或优于3×10^-5 m/s²的精度.

Abstract: The two methods including Poisson integral and point masses are used to evaluate the accuracy of airborne gravimetry data in Australia West Arnhem Land. The results show that the accuracy of Australia airborne gravimetry data are respectively 2.81×10^-5 m/s² and 2.95×10^-5 m/s² according to the 2'resolution, and the accuracy of 5'resolution is better than 3×10^-5 m/s². The Bohai airborne gravimetry using CHAGS system is evaluated by using the crossover point adjustment and Poisson integral method, the analysis results show that the two estimation modes has different accuracy value. Based on the external land and sea gravity data, the Bohai airborne gravimetry has the accuracy better than 3.5×10^-5 m/s² according to the 5'resolution although the data has the 3×10^-5 m/s² systematic error. In the coastal area, the accuracy of airborne gravimetry is affected by the performance of surveying system, and the general accuracy of airborne gravimetry is about or better than 3×10^-5 m/s² according to the 5'resolution.
