Deviation (errors mainly caused by shipboard enviroment) can be automatically corrected by swinging the boat. The PG-500 can provide true heading by using its correction facilities for magnetic deviation and variation. Unlike an ordianary fluxgate that only outputs sine/consine data, the PG-500 outputs the heading data in the format of IEC 61162, NMEA 0183, or Furuno AD-10 format. ![]() The processor monitors the coriolis force output by the solid-state rate gyroscope and stabilises the compass heading. The sensor detects the heading relative to the magnetic north as induced within the fluxgate coils by terrestrial magnetism. The PG-500 consists of a fluxgate sensor, solid-state rate gyroscope, processor and serial data interfaces. The Furuno PG-500 is an inexpensive magnetic heading sensor for pleasure craft and coastal fishing boats. Waterproofing: IPX5 (IEC 60529), CFR-46 (USCG standard). ![]()
