摘要
舰船的磁场是舰船物理场的重要信息,对它的测量对研究舰船物理场的特征具有重要的意义。然而,在海水中舰船的磁场信息势必受到舰船姿态信息变化的影响,因此提出修正舰船姿态信息对磁场测量影响的方法。本文具体论述了用船载GPS姿态仪获取舰船姿态信息的原理和实现方法,并提出了用舰船姿态信息修正舰船磁场的计算方法,从而提高舰船磁场的测量精度。
The magnetic field of the ship is the important information of the physical flied of the ship.So measuring the magnetic is significant for getting the characteristic of the ship＇s physical field.We advance the method of modifing the results of the magnetic field measure which are influenced by the ship＇ attitude.We discuss about the theory and the realizable method of using the instrument of GPS attitude on the ship and advance the way to modify the magnetic field of the ship using by the information of the ship in order to improve the metrical precision of magnetic field.
