KSS32-M型海洋重力仪动态性能分析
Dynamic performance testing of the KSS32-M marine gra-vimeter
摘要
Abstract
Based on the data measured using the KSS32-M ocean gravimeter in recent years, the measurement sta-bility and data reliability of this instrument are analyzed; moreover, the methods employed to measure the intersec-tion point difference, repeating survey line, and coincidence line using the gravimeter are compared. The delay time of the gravimeter is 70 s, calculated using the maneuver steering method. Based on this calculation, the accuracy of gravimetric measurement is found to be 0.65 mGal. According to the gravity profile collected by the gravimeter, the correlations of the coincidence lines are highly correlated. The absolute value of the intersecting point difference of four coincident surveying lines is 1.66 mGal, and the precision is 0.59 mGal. All data meet the national standard of the intersection which the gravity measurement network of the national standard of the intersection point difference that less than 2 mGal. The average value of the anomalies of the matching points is less than 0.9, the variance is less than 0.8, and the correlation is higher than 0.98. In summary, this study shows that the data measured by the KSS32-M gravimeter are stable and reliable.关键词
