【摘要】 本文对捷联式惯导系统初始对准的陀螺罗经法和匹配法进行了比较研究，揭示了两者之间存在的相似性。从理论上提出一种新的匹配对准算法，该算法可以消除由于挠曲变形所引起的角速度干扰。本文还引入一种特殊的坐标变换，说明这种匹配算法与罗经法具有相同的数学形式更多还原

【Abstract】 Gyrocompassing and rate acceleration matching are regarded as two separate kinds of initial alignment for strapdown INS. Presented in this paper, however, is a comparative analysis of the two, and an analogy between them is demonstrated. Then, by analogy with gyrocompassing a new algorithm is devised for matching alignment, this algorithm is capable of isolating the angular perturbation induced by the structural flexure. Through a special coordinate transformation, this matching alignment turns out to be identical with gyrocompassing in mathematical structure.更多还原
