摘　　要：针对平台式惯导系统阻尼系统设计复杂的问题,根据罗经对准网络与阻尼网络的等效性,研究一种新的捷联阻尼算法。以捷联式惯导系统的数学平台代替平台式惯导系统的实体平台,设计捷联式惯导系统阻尼网络,包括水平阻尼网络和全阻尼网络,推导方便计算机运行的水平阻尼算法和全阻尼算法。结合某型激光陀螺双轴旋转惯导系统半实物仿真,对水平阻尼和全阻尼算法进行验证。According to designing of platform inertial navigation （ algorithm of strapdown inertial navigation （SINS）is proposed in this paper INS ） complex, for equivalence new damping with compass alignment network and damping network. Substituting Physics platform of platform INS by mathematical platform of SINS, damping network of SINS is designed, which includes level damping networking and full damping network. Corresponding level damping algorithm and full damping algorithm to facilitate computer running are calculated out. Combined with a certain type of dual-axis rotating laser gyro INS,Semi-physical simulation is carried out to verify the level damping algorithm and the full damping algorithm.
