摘要
针对当前新型号导弹武器无依托发射时惯导参数标定及战略导弹核潜艇导航定位的现实需求,针对我国重力测量精度低、依赖进口的现状,介绍了原子干涉重力仪的基本原理和近年来国内外主要发展状况.分析了近年来国外仪器测量精度有所提升,但存在实用化、产品市场化不足的特点,国内主要存在测量精度低、技术体制单一及环境适应性差的主要差距,展望了原子干涉绝对重力仪的发展方向.
Aiming at the new type missile weapons need to be calibrated for inertial navigation.The strategic missile nuclear submarines need navigation and positioning during sailing,the basic principles of atomic interference gravimeter and the main study developments of domestic and abroad are introduced in this paper.The measurement accuracy of foreign instruments has been improved in recent years,but there are a few insufficient character in practicality and marketization of products.The main problems have analyzed in China,such as low measurement accuracy,single technical system and poor environmental adaptability.The development direction of atomic interference absolute gravimeter is prospected.
