摘　　要：误差源考虑不全面、计算误差不简便是目前分析挠性陀螺寻北仪的寻北误差时存在的两大问题。根据寻北误差对寻北结果的影响，可以从宏观上全面考虑所有的误差源，通过分析陀螺寻北仪输入输出之间的关系，将寻北误差分成了三个独立的类型；针对分析第二类误差时存在的计算误差不简便的问题，通过引入误差角x、ξ和δ，分析各坐标系之间的关系，建立了一个统一的误差解算模型。There are two problems to analyze the error of full position Dynamically Tuned Gyro （DTG） north - seeker, the first one is unilaterally considering the error and the second one is complexly calculating the error. To solve these two problem, all errors are took into full consideration from macro-view according to the effect of the error to the north finding result. The errors are divided into three absolute types according to the relationship between the in and out of the flexible gyro. A uniform model to solve the error of the second error type is set up through error anglex, ξ andδ.
