航空重力起伏飞行中飞机姿态对测量数据影响分析

摘要

Under the condition of airborne gravity drape flying, the authors employed the GT-1A airborne gravity system to explore whether changes in aircraft attitude could affect the airborne gravity data and to test the possibility of applying the slight slope drape fly-ing to gravity survey. The authors collected data from the same line with two kinds of rate of climb ( 1m/s and 2m/s) , and the results showed that there were no significant differences in the airborne gravity data between these two drape flying conditions. The findings im-ply that the GT-1A airborne gravity system could be applied to airborne gravity survey with drape flying.%在航空重力飞行时，针对GT-1A航空重力系统在同一条测线中使用两种爬升率（1 m/s和2 m/s）进行起伏飞行。考察起伏飞行引起的飞机姿态变化对测量数据的影响，以及在航空重力测量中小坡度缓起伏作业的可行性，是笔者的研究目的。试验结果表明，所使用的两种爬升率对航空重力测量数据未有明显影响，GT-1A航空重力系统可以进行缓起伏飞行测量。
