BG ZG100 GPS Antenna with Compass

ZG100 GPS Antenna

Take your marine navigation to the next level with the B&G ZG100 GPS Antenna — a high-performance unit combining precision positioning with onboard heading, heel, and trim sensing. Designed especially for sailboats and performance vessels, this antenna delivers real-time data for chartplotters, instrument systems, and NMEA-2000® networks.

The B&G ZG100 is a compact, rugged GPS antenna with a built-in electronic compass and inertial sensors. Its 10 Hz update rate ensures smooth, accurate tracking even during high-speed maneuvers or under acceleration. Because heading is integrated, chart overlays, radar stabilization, and autopilot direction (where supported) benefit from real-time heading data without needing a separate compass unit. Optimized signal acquisition and support for WAAS, EGNOS, MSAS (and more) help maintain stable fixes in challenging conditions.

Key Features & Capabilities

• 10 Hz position update rate for rapid, smooth fixes during maneuvers 
• Integrated electronic compass provides heading data for chart stabilization, “Head-Up” mode, and radar overlays 
• Heel & trim sensor for sailing load compensation and advanced routing 
• Sail-specific COG/SOG filtering for optimized performance under sail 
• Support for GPS and augmentation systems like WAAS, EGNOS, MSAS, and compatibility with Galileo & QZSS NMEA-2000 interface (Micro-C) for seamless integration with modern marine networks Low power consumption (< 2 W typical) with 9–18 V DC supply and reverse-polarity protection 
• Rugged, weatherproof housing (IPX7 or better) to endure harsh marine environments 
• Compact dimensions (≈ 90 mm diameter × 38 mm height) and light weight (~0.14 kg / 0.30 lbs) for flexible installation 
• Operating temperature range from –25 °C to +60 °C (–13 °F to ~149 °F) and storage range to –40 °C / +85 °C

Compatibility & Use Notes

• This model (000-11048-002) is optimized for B&G chartplotters and instrument systems, and works best when connected via NMEA-2000 to other marine electronics (e.g. displays, autopilots, radar) 
• Not suitable for use with MARPA or B&G Pilot systems that require a rate compass — those systems need dedicated rate compasses such as the Precision-9 or RC42 
• For best performance, mount where the antenna has a clear view of the sky and is away from magnetic interference — avoid nearby wiring, metallic structures, below-deck mounting in some cases
