Discover Superior Navigation with the B&G ZG100 GPS Antenna

Imagine slicing through choppy waters with pinpoint accuracy on your charts, no matter how fast you're accelerating or tacking. The B&G ZG100 GPS antenna delivers exactly that—reliable, high-speed position data tailored for serious sailors. Paired seamlessly with B&G chartplotters and instruments via NMEA 2000, it transforms raw satellite signals into smooth, actionable insights for speed, course, and heading.

What sets it apart? Its 10 Hz update rate means your display refreshes position info up to 10 times per second, banishing the jittery lines you get from slower antennas. Add in sail-specific filtering for course over ground (COG) and speed over ground (SOG), and you've got performance optimized for the unpredictable dynamics of sailing—perfect for tight maneuvers or racing starts.

Key Features That Elevate Your On-Water Experience

• Multi-GNSS Precision: Locks onto GPS, GLONASS, and more, with WAAS, EGNOS, MSAS augmentation for sub-meter accuracy worldwide. Galileo-ready via future updates.
• Integrated Sensors: Built-in rate-stabilized compass for true heading, plus heel and trim sensors to keep your data steady even when the boat heels over.
• Smooth, Responsive Updates: 10 Hz GPS refresh rate ensures fluid chart overlays and radar stabilization without lag.
• Rugged Marine Build: IPX7 waterproof rating shrugs off splashes and submersion, thriving from arctic blasts to tropical heat.
• Compact and Versatile: Slim 3.54-inch diameter fits anywhere—flush mount or pole—with a 21-inch compass-safe distance for interference-free operation.
• NMEA 2000 Plug-and-Play: Connects effortlessly to your network, sharing data across displays without fuss.

Pro tip for racers: The ZG100's low-speed COG filtering shines in light winds, giving you confidence in laylines and wind shifts without the noise of basic GPS units.

Detailed Technical Specifications

These specs make the ZG100 a workhorse for offshore passages or coastal cruising, where every degree and meter counts.

What's Included for Hassle-Free Setup

• ZG100 GPS Antenna with integrated sensors
• 1.82m (6ft) NMEA 2000 extension cable
• Micro-C T-connector for easy network integration
• Pole mount bracket for flexible positioning

Everything you need to mount and connect right out of the box, minimizing downtime on the water.

Installation Insights for Optimal Performance

Position the ZG100 high and clear of obstructions for the best sky view—think masthead or radar arch. Its compact size and included pole mount make this straightforward. Power it via your NMEA 2000 backbone (9-18V), and it'll auto-configure on compatible B&G systems. Keep compasses at least 21 inches away to avoid deviation. Sailors often praise its quick reacquisition after tacking, locking back in under 5 seconds.

Important note: While excellent for charts and overlays, it's not rated for MARPA target tracking or autopilot steering. For those, pair with a Precision-9 compass.
