DH-V Type Electromagnet Control Gyrocompass

Main function:

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.

Main property index:

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