影响航空重力测量质量的若干因素分析

航空重力测量过程中会受到多种因素的影响,找出影响因素并量化其影响程度对于提高测量质量至关重要。从GPS测量、飞行姿态、重复线内符合精度3个方面分析影响航空重力测量质量的因素,针对每种因素提出解决方案和实施过程中应遵照的相应原则,并利用试验数据验证解决方案的有效性和合理性,为大规模开展航空重力生产和研究提供参考依据。

Analysis on some factors of influencing airborne gravity survey quality

Airborne gravity survey process will be affected by many factors,for which the causes and quantified incidence are very important to improve the quality of measurement. From the GPS measurement,flight attitude,and internal accord accuracy of repeat line,this paper analyzes the influence factors on the quality of the airborne gravity survey,solutions and principles.Complied with the implementation process put forward for each factor,the test data is used to verify the validity and rationality of the solution,which can provide a reference for the large-scale airborne gravity production and research.
