摘要
提高精度与降低成本是惯性技术发展永恒的主题,误差自补偿技术是符合该主题的重要研究方向之一。惯导系统可通过其特有的旋转机构及其周期性运动,实现惯性仪表误差的自动补偿,从而达到提高系统精度和降低系统成本的目的。论文在综合分析国内外大量相关资料的基础上,重点对国外惯导误差自补偿技术的起源、发展和应用情况进行了研究分析,同时对国内数家单位的研究工作也进行了总结,供该领域研究工作者参考。
To improve the precision and reduce the cost is the eternal theme of inertial technology development, error self - compensation technology is one of the important research directions consistent with the theme. Inertial navigation system can realize error self - compensation for system or inertial device through unique structure （ mainly rotating mechanism） and periodic motion, so as to improve the precision of the system and reduce the system cost. Based on comprehensive analysis of a large number of domestic and international references, the origin, development and application of foreign error compen- sation technology are focused on and analyzed, including Europe and the United States in the early studies, roulette Trojan technology, rotating modulation technology. At the end several domestic research work are summarized. Through summary and comparison of the domestic and international related research work, the paper hopes to provide some ideas and refer- ence value for some related researcher.
