【摘要】 为检验我国首套航空重力测量系统(CHAGS)对轻小型固定翼飞机的适应性以及验证CHAGS在严寒气候条件下的作业性能,2003年11月以国产某新型航测机为载体在我国东北某地区进行了试验。本文概述了试验情况,介绍了航空重力测量数据处理方法。试验结果表明,CHAGS工作稳定、性能可靠,交叉点重力异常不符值的标准差为1.9mCal,相应的半波长分辨率约为9km。
【Abstract】 To check the applicability of the Chinese airborne gravimetry system (CHAGS) to the light-small fixed wing aircraft and the feasibifity of the CHAGS under the cold conditions, a test was conducted over the Northeast China in November 2003. We summarized the test and introduced the processing method of the aerial observed data in this paper. The results indicated that CHAGS is working well and has good performance. The standard derivation of the crossover errors is about 1. 9mGal with the wavelengths resolution of 9km.
