激光陀螺在民用和军用飞机的新型惯性导航系统中业已占有压倒优势,目前在极高精度的应用方面又向传统陀螺提出了挑战,这些极高精度的应用包括洲际弹道导弹及其可操纵重返大气层运载火箭。十年前,一般认为激光陀螺只不过是具有中等精度的适用于短程战术导弹的一种装置。 Laser gyros are overwhelming in new inertial navigation systems for both civil and military aircraft and present challenges to conventional gyroscopes in extremely high precision applications such as ICBMs and their re-entry Atmospheric carrier rocket. Ten years ago, laser gyros were generally considered to be just a medium-precision device for short-range tactical missiles.
