惯性导航是一种完全自主、抗干扰能力强的导航方式,因受限于惯性器件的灵敏度和长期稳定性,惯性导航系统定位精度相比于卫星导航仍有较大差距。新型的基于原子干涉技术的惯性敏感器件在理论上具有灵敏度高、长期稳定性强和实时消除重力偏差的特性,具有推动惯性导航技术到达卫星导航性能的潜力。介绍了近年来欧美研究机构在原子干涉惯性敏感器的工程化研制上取得显著进展,总结了原子干涉在惯性导航领域的技术发展方向。
Inertial navigation is a completely autonomous, anti-interference ability of navigation, due to limited the inertial device sensitivity and long-term stability, inertial navigation system positioning accuracy compared to satellite navigation is still a big gap. The new inertial sensor based on atomic interferometry has the theoretic properties of high sensitivity, long-term stability and real-time elimination of gravity deviation, which has the potential to promote inertial navigation technology to reach the performance of satellite navigation. In recent years, the research institutions in Europe and the United States have made remarkable progress in the engineering development of inertial sensors for atomic interference, and summarized the technical development direction of atomic interference in the field of inertial navigation.
