摘要
论述了磁悬浮寻北仪的结构组成,在分析寻北过程中寻北仪的力矩关系基础上,讨论二位置寻北方案。陀螺仪在相差180°的两个位置寻北,转位对消陀螺仪常值漂移,可有效提高寻北精度和缩短寻北时间,系统简单,容易实现。探讨转位误差影响,推导出转位误差与寻北误差之间的关系表达式,为转位误差的补偿提供了理论基础。
Structural component of magnetic suspension gyroscope is introduced. The relation of torquein the north-seeking progress is analyzed and the two-position north-seeking scheme is discussed. Gyroscope seek north at two azimuths with a phase difference of 180°, the constant drift is cancelled by position transformation. North-seeking precision and north-seeking time is sharply improved. The structure of north seeker is simple and its seeking scheme can be easily implemented. The influence of position transforma- tion error is explored. The relational expression between position transformation error and north-seeking er- ror is derived, which can provide theory foundation for position transformation error compensation.
