摘　　要：为满足舰载光纤陀螺捷联惯导系统初始对准的快速性和高精度等要求，本文对三种不同的快速粗对准算法进行了比较研究和实验，重点对罗经法精对准进行了理论分析，并通过三轴转台上的各种静动态实验验证了各算法的精度和快速性。试验结果表明：静止基座航向角对准精度优于0．07°，摇摆基座航向角对准精度优于0．1°，完成对准需、500秒，能够达到实际应用的要求。To meet the requirements of rapidity and high precision of initial alignment for SINS used on ships based on fiber optic gyroscope, comparison and experiments are implemented for three rapid coarse alignment methods. The precise com- pass alignment theory is analyzed. The precision and efficiency has been validated by stationary and swinging base experiments on three-axis rotation table. The results indicate that the heading angel alignment accuracy is below 0.007 degree on stationary base while 0.1 degree on swinging base. The whole alignment time is around 500 seconds.
