摘　　要：冷原子技术是一种量子精密测量技术,能够高精度、高空间分辨率测量重力信息,并具有动态测量能力。目前在高精度绝对重力测量、海空重力测量,以及卫星重力测量应用中受限于传统重力测量技术的物理极限,难以实现亚微伽级和动态绝对重力测量,限制了重力测量应用的发展。通过总结冷原子绝对重力技术进展和当前重力测量应用需求,分析了未来在冷原子技术驱动下的重力测量应用发展趋势。Cold atom technology,one of the quantum precision measurement technology,can carry gravity survey with high-precision,high-spatial resolution and on moving platform.In the applications of high-precision absolute gravity survey,marine&airborne gravity survey,and space gravity survey are limited by physical limits of traditional gravimeter,and it is hard to reach sub-micro Gal order and dynamic measurement,which restricts the application of gravity survey.Based on summarizing the progress of cold atom absolute gravimeter and the demand of gravity survey,this paper analyses the development tendency of gravity survey driving by cold atom technology in the future.
