DH-V Type Electromagnet Control Gyrocompass

DH-V Type Electromagnet Control Gyrocompass adopt Two-freedom gyroscope and electromagnetic pendulum as sensitive element,it take adavantage of gyroscope features and rule of earth rotation, make the device find north automatically and point the north stable.The device adopt digital control technology from the aspect of find north automatically, error compensation, easy to operate, stable and reliable.

a.find north automatically: compass take advantage of gyroscope features, the rule of earth rotation, through the control system to make the gyro shaft possess find north fast and automatically.

b. latitude,speed error error compensation function. c.course value indication function.

d. port function:possess the port function can send course signal to load.

e.alarm function: possess gyroscope power fault,servo system fault,interior CAN network mailfunction,velocity anomaly of course angle,input speed/latitude information abnormal warning function.

The main property index of DH-V type electromagnet control gyrocompass is satisfy A.424(XI) IMO resoluation and ISO8728:1997.

a.Accuracy index
