B&G ZG100 GPS Antenna Product Description
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.

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.
Frequently Asked Questions
What satellite systems does the B&G ZG100 support?
It supports GPS and GLONASS natively, with augmentation from WAAS, EGNOS, and MSAS for enhanced accuracy. It's also QZSS-ready and Galileo-capable via software updates.
How fast does the ZG100 update position data?
Up to 10 Hz, providing 10 updates per second for incredibly smooth tracking during high-speed maneuvers or rapid direction changes.
Is the ZG100 waterproof for marine use?
Yes, it boasts an IPX7 rating, fully submersible for up to 30 minutes, making it ideal for harsh saltwater environments.
Does it include a heading sensor?
Absolutely—an integrated rate-stabilized compass delivers ±3° heading accuracy, plus heel and trim compensation for stable data on heeled sails.
Can the ZG100 drive an autopilot?
No, it's designed for position, speed, and heading display/chart stabilization—not MARPA or autopilot control. Use a Precision-9 for those functions.
What's the power requirement for installation?
Operates on 9-18V DC via NMEA 2000, drawing less than 100 mA at 12V—efficient for most boat systems.
How do I mount the ZG100 for best results?
Use the included pole mount or flush mount it high with a clear sky view. Maintain 21 inches from compasses to prevent interference.
