摘　　要：针对传统方法计算磁罗经自差系数效率低、描绘自差曲线不平滑、制定自差表不准确等问题,以自差原理和爱利法为基础,设计并实现了磁罗经自差校正准确性评估软件,采用广义最小二乘估计方法求解自差系数,自动绘制自差曲线和生成自差表,并可根据训练与考核大纲中相关标准评估自差消测效果,具有简便准确高效的特点;已应用于教学及出海实习训练,对于提高学员的任职能力具有较强实用性,并可为舰船消测磁罗经自差等科目训练考核提供辅助和参考,对保证磁罗经工作精度具有重要作用。Aimed at problems of traditional method for magnetic compass deviation correction, such as inefficiency for calculations of deviation coefficients, unsmoothness of deviation curve description, and inaccuracy of deviation tabulation, the paper designed and realized an accuracy estimation software for magnetic compass adjustments based on deviation principle and Airy method. By general least squares estimarion, the software can solve deviation coefficients, draw deviation curve, and generate deviation table automatically. It can estimate the effect of deviation correction according to related standard of training and examine outline, its process is simple, exact and efficient. When ap plied to teaching and practices on the sea, the cadets＇ working ability was enhanced. It provides auxiliary and reference for deviation correc- tion subjects in warships, and guarantee operating precision of magnetic compasses.
