航空重力起伏飞行中飞机姿态对测量数据影响分析

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。

The impact of aircraft attitude on the measurement of airborne gravity survey under drape flying

Under Ihe eonditinn of airborne gravity drape flying, tile authors employed the GT-IA 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 tlying to gravity survey. The authors collected data from the same line with two kinds of rate of elimb （ 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 imply thal the GT-IA airborne gravity system could be applied to airborne gravity survey with drape flying.
