摘　　要：　近十几年来,航空重力测量技术的研究和应用日趋活跃,业已成为地球重力场研究中最为热门的领域之一.航空重力测量可分为航空标量重力测量、航空矢量重力测量和航空梯度重力测量.本文概述了航空标量重力测量的研究现状及发展动态,传统航空重力测量系统的改进,新型系统方案的研究,从GPS中导出加速度的理论和方法,滤波和估算方法及航空重力数据的应用等五个方面的重要研究成果.文中最后介绍了我国自行研制的航空重力测量系统的概况.Airborne gravimetry has been rapid development during the past decades and becomes one of the very active topics of the research in the gravity field. It shows three different approaches to airborne gravimetry, namely scalar gravimetry, vector gravimetry and gravity gradiometry. Recent activities for the airborne scalar gravimetry are summarized in this paper, they includes five aspects, viz. improvement of traditional airborne scalar gravity systems, development of new system concepts, optimization of acceleration deriving from DGPS, optimization of filtering and estimation methods, and the application of airborne gravity data in various mapping and exploration applications. Finally, the Chinese airborne gravimetry system that has broke into success in 2002 is introduced briefly.
