摘　　要：为有效提高挠性陀螺寻北仪的寻北精度引入了基于误差角的寻北误差模型，从理论上分析了误差角和方位角的变化对寻北误差的影响，通过仿真进一步证明了理论分析的正确性，仿真结果还表明当方位角为0°或180°时由误差角引起的寻北误差将达到最大值，当误差角在0～1′变化时引起的最大寻北误差为24′，当误差角在0～30”变化时引起的最大寻北误差为9′，当误差角在0～10″变化时引起的最大寻北误差为3′，当误差角在0～1″变化时寻北误差接近为零。The error model based on the error angle has been introduced to improve north-seeking precision of DTG. The changing rules of the north-seeking error with the error angle and azimuth angle are analyzed theoretically, and which correctness is proved by simulation. The simulation results also show that when the azimuth angle is 0° or 180°, the northseeking error will reach its maximum by the error angle. The maximum north-seeking error will reach to 24′, when the error angle changed between 0 to 1′, and which will reach to 9′ when the error angle changed between 0 to 30″, and which will reach to 3′ when the error angle changed between 0 to 10″, and which will be close to zero when the error angle changed between 0 to 1″.
