Garmin becomes first major consumer marine manufacturer to offer multi-band GPS with both L1 and L5 frequencies

New features in GPS 24xd marine antenna provide heading and positioning accuracy to within 1 meter

OLATHE, Kan. — Garmin International, Inc., a unit of Garmin Ltd. (NASDAQ: GRMN), the world’s leading marine electronics manufacturer, today announced the GPS 24xd marine position receiver and antenna with multi-band GPS, offering mariners the most advanced positioning and heading data available. The GPS 24xd utilizes both L1 and L5 frequencies, along with multi-constellation support (GPS, Galileo, GLONASS, BeiDou), to provide multi-band GPS capability enabling location accuracy within 1 meter. Thanks to built-in magnetic heading sensors, it’s possible to pinpoint heading within 3 degrees, which in turn delivers optimum chart stability, radar overlay and mini-automatic radar plotting aid (MARPA), even at slower speeds.

“We remain ambitious about our mission to provide the most innovative and cutting-edge marine technology on the market today, and we believe that the GPS 24xd is a testament to that commitment,” said Dan Bartel, Garmin vice president of global consumer sales. “Using innovative multi-band GPS, we are confident that the new GPS 24xd will provide Garmin customers with the highest level of reliability and precision for their cruising, fishing and sailing adventures.”

Advanced Positional Performance

Mariners can now experience the unrivaled accuracy of the GPS 24xd antenna while cruising the water at any speed. Built on the foundation of the existing GPS 19x, the GPS 24xd offers revolutionary multi-band technology, the first of its kind in the consumer marine industry, and 10Hz position update rates for the finest high sensitivity tracking the market has to offer. These new features are accompanied by expanded compatibility with GPS, Galileo, GLONASS and BeiDou satellite constellations to provide boaters across the globe with consumer market-leading accuracy on the water, no matter the condition, distance or destination.

Reliable Magnetic Heading

An added magnetic heading sensor allows boaters to better maintain chart stability and radar overlay, regardless of speed. By delivering heading accuracy within +/- 3 degrees, this magnetic sensor makes the GPS 24xd ideal for slow cruising, when GPS COG (Course Over Ground) data can become less reliable.

Multi-SBAS Compatibility

To further its high sensitivity tracking on the water, the GPS 24xd includes Multi-SBAS (Satellite-Based Augmentation System) compatibility to correct signal measurement errors and provide rich information regarding signal accuracy, integrity, continuity and availability. This extended compatibility ensures that boaters always know exactly where they are headed while navigating to their next waypoint.

Pricing and Availability

The GPS 24xd series is available now with a suggested retail price of $299.99, which includes a pole mount, surface mount and under-deck mount for easy installation on any boat. It’s available for both NMEA 2000 and NMEA 0183-capable Garmin marine chartplotters, including the award-winning GPSMAP® series. For more information, visit

    It looks GPS signal L5 is not completely operational yet, but it’s nice to see that it’s “designed to meet demanding requirements for safety-of-life transportation and other high-performance applications.”

    And, hey, is there any other GPS sensor available for $299 with an included Heading sensor good enough for “chart stability, radar overlay and mini-automatic radar plotting aid (MARPA), even at slower speeds”?

    I notice that Garmin doesn’t mention using the Heading with an autopilot, but still this may be the big news here?

    Looks like Garmin device only compatibility. How hard would it be to make it compatible across the spectrum? How smart would it be?

    Wonder when Garmin will come with a GPS Compass? Being the GPS company.

    Let’s expect this surprise in 2021. 😉

    For a bit more dough, (OK more than a bit) one could have a Furuno GPS Compass SCX20 which is good to 0.5 degree and will really steady your autopilot and RADAR overlay down. Magnetic compasses are so last year. 3 degrees of accuracy, Meh… With my sat compass the autopilot will hold course to less than 20 feet of the route line 95% of the time even through turns.

    I tested the GPS24xd in the workshop and the position accuracy from the last 7 hours is good in the range of 0.9 0.5m.
    I have a photo of the TZT3 from the sky view, but I can’t edit it on Panbo.

    OK sent .

  8. Christopher says:

    Measurements made in the workshop, so almost 60 m above sea level, GPS on one side NW covers the wall of the building which still gives a very good position result, comparable to the SCX-20 located in the same place.
