摘　　要：冷原子技术具有低频噪声功率谱平坦、测量范围大、稳定性高、共模抑制效果好等优点,有望成为未来重力卫星的备选技术之一。本文基于冷原子重力梯度仪和冷原子钟,提出了2种基于冷原子技术的卫星重力测量方案,为未来高分辨卫星重力测量提供参考。With the advantages of high stability,large range,wide measurement bandwidth,smooth lowfrequency white noise spectrum,and high common mode rejection,the technology of cold atom is expected to be one of the alternative technologies for future gravity satellites.In this paper,two satellite gravity measurement schemes based on the cold-atom gravity gradiometer and cold-atom clock are proposed to provide reference for future highresolution satellite gravity measurement.
