摘要
根据航天测量船结构特点,分析测量船磁罗经的受力以及罗经自差变化的原因,针对测量船航线途径磁赤道的航程,提出准确校正测量船磁罗经自差及保证自差系数稳定的方法。
The force state of magnetic compass and the reason of compass deviation modification are analyzed,according to the structural features of the space tracking ship.Taking the chance of ship line via magnetic equator,a method is presented to provide accuracy correction for magnetic compass deviation and keep deviation coefficient maintain stability.
