B&G ZG100 GPS Antenna with Compass NMEA2000

The ZG100 Antenna with built in rate compass provides high accuracy position at a 10Hz update rate. The built in rate compass is perfect for for providing heading data for Radar Chart Overlay and for orenting charts in Head Up Mode. Note: This heading sensor is not recommended for MARPA or Autopilot control. We recommend the Precision9 for this purpose.
