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 flying 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 imply that the GT-1A airborne gravity system could be applied to airborne gravity survey with drape flying.
