【摘要】 研制了一种磁罗经自差自动测定和补偿系统,通过比较磁阻传感器的航向和陀螺罗经航向,自动地获得罗经自差,在对罗航向补偿后可直接显示船舶磁航向或真航向.该系统还可自动计算出自差系数,用于船靠码头时校正罗经自差.经过实船检验,证明了其可行性.更多还原

【Abstract】 this paper researches and produces a system for automatically measuring and compensating magnetic compass deviation. After comparing the course of magetoresistive sensor with the course of gyrocompass, automatically obtain compass deviation and as soon as the magnetic compass heading is compensated, directly display ship’ magnetic course and true course. The system automatically calculates deviation coefficients for correcting deviation when ship gets alongside the wharf. After inspecting on a real ship, the system is proved available for use.更多还原
