Why is the traditional magnetic compass error large? One is without compass deviation correction; two is the magnetic variation in different regions is different, there is no real correction.
GP-700 type magnetic compass sensing compound will solve the above problems; automatically converted into digital magnetic compass heading signal, and the real-time magnetic deviation compensation, automatic deviation correction. It can accurately display the heading data and output NMEA-0183 signals (HDM, HDT or AD-10) for the use of radar, autopilot, electronic chart, AIS and other equipment.
