About the Garmin GPS 24xd NMEA 2000®
Precise location accuracy
Precise location accuracy
Garmin's GPS 24xd marine position receiver and antenna works with your chartplotter, sonar, or other marine navigation instruments to provide you with the information you need for confident navigation. It features multi-band GNSS for precise location accuracy to within one meter, while its magnetic heading sensor is accurate to within three degrees, even at slow speeds. The fast 10 Hz position update rate means you'll always have accurate speed, position, and time information.
Works with multiple satellite systems and mounting options
The GPS 24xd works with four key global navigation satellite systems (GNSS), so you're sure to find a signal no matter where you're boating. And It includes surface-mount, under-deck, and pole mounting hardware so you can add the antenna to your craft safely and unobtrusively.
Water resistant and NMEA 2000 compatible
The GPS 24xd's IPX7 water-resistance rating ensures dependable performance in the stormiest of conditions. And it works with all devices supported by the NMEA 2000 protocol, so you can build out your system with confidence.

More details on the Garmin GPS 24xd NMEA 2000®
Overview: The Garmin GPS 24xd receives location signals from multiple overhead satellite positioning satellites to provide your boat with an accurate location, velocity, and heading. It is compatible with NMEA 2000 devices, and works with most Garmin echoMAP and GPSMAP marine chartplotters. The antenna should be mounted in a location with a clear, unobstructed view of the sky in all directions. The GPS 24xd comes with a variety of mounts and a 6-meter NMEA 2000 drop cable and T-connector.
Multi-Band GNSS: The GPS 24xd uses multiple Global Navigation Satellite Systems (GNSS) to provide accurate location (to within 1 meter) and headings (to within 3 degrees). In addition to the U.S.-based GPS (Global Positioning System), the GPS 24xd employs Russia's GLONASS, Europe's Galileo, and China's satellite navigation system BeiDou. Using multiple systems provides better accuracy, especially in challenging conditions, compared to using GPS alone. In addition to your position and heading, the GPS systems also provide precise time data.
Positioning Updates: The GPS 24xd High Sensitivity GPS updates your position at a rate of 10 times per second (10 Hz). This provides an accurate reading of your position on the map, but also gives you reliable measurement of your navigation speed.
Magnetic Heading: The magnetic heading sensor is accurate to within 3 degrees, even at slow speeds. After installation, and before use, you must calibrate the heading and perform the auto heading alignment to receive magnetic heading data.
Multi-SBAS Compatible: The device is compatible with multiple SBAS (Satellite Based Augmentation System) networks to correct signal measurement errors. SBAS uses a number of geostationary satellites, and a network of ground stations, to increase the integrity and accuracy of the positioning systems. SBAS reduces position errors to less than 1 meter. EGNOS (European Geostationary Navigation Overlay Service) is the European version of this system, while WAAS (Wide Area Augmentation System) is the U.S. version.
NMEA 2000: The positioning data is routed to your chartplotter via a NMEA 2000 network. If your boat doesn't have a NMEA 2000 network, one will need to be installed. The GPS 24xd is packaged with a NMEA 2000 T-connector and a 6-meter NMEA 2000 drop cable, which are needed to connect the antenna to an existing NMEA 2000 network. A shorter drop cable can be used, if desired.
Waterproof Construction: The GPS 24xd's outer case is made of high-impact plastic alloy, and is fully gasketed to a waterproof rating of IPX7. The device withstands incidental exposure to water up to 1 meter for up to 30 minutes, and is protected against powerful jets of water.
Mounting Options: The GPS 24xd comes with a variety of mounts for installing the antenna in the following ways:
- Surface: The included surface mount lets you install the antenna on a flat surface. The bracket is attached to the surface with the included stainless steel screws. You will need a drill with a 1/8" drill bit, a countersink bit (if mounting on fiberglass), and a 1" hole saw for routing the cable.
- Under Deck: The included under deck mount lets you install the antenna underneath a fiberglass surface. The antenna cannot acquire signals through metal. You will need a drill with a 1/8" drill bit for the screw holes, and provide the appropriate screws.
- Pole: The antenna can be mounted to a pole using the included pole-mount adapter. The adapter screws onto a standard 1" OD, 14 threads-per-inch, pipe-threaded pole. The cable can be routed outside or inside of the pole, as desired. No drilling is needed for the pole mount.
