Maretron GPS Antennas: Precision Positioning for the Connected Vessel

When it comes to integrating accurate positioning data into a modern marine electronics network, Maretron stands in a class of its own. As a world leader in vessel monitoring and control systems, Maretron has built its reputation on engineering products that speak the language of the sea — specifically, the NMEA 2000® protocol. Their GPS antenna and receiver offerings bring that same philosophy to onboard positioning, delivering precise, network-ready location data that feeds directly into the heart of any NMEA 2000®-equipped vessel.

The GPS200: Maretron’s Flagship GPS Antenna/Receiver

The cornerstone of Maretron’s lineup in the GPS, Cellular & WiFi Antennas category is the GPS200 GPS Antenna/Receiver. This unit is a state-of-the-art 99-channel GPS/GLONASS antenna and receiver capable of delivering ten position fixes per second, accurate speed-over-ground data ten times per second, and precision time output once per second — performance metrics that matter when you’re navigating in real time.

What sets the GPS200 apart from generic marine antennas is its deep integration with the NMEA 2000® ecosystem. As a fully certified, plug-and-play NMEA 2000® device, it connects directly to any compatible network backbone and immediately begins sharing data — latitude, longitude, course over ground (COG), speed over ground (SOG), date, time, and satellite status — with chart plotters, autopilots, multifunction displays, and vessel monitoring software like Maretron’s own N2KView® and DSM-series color graphics displays.

WAAS and Multi-System Augmentation for Superior Accuracy

Positional accuracy is critical offshore, and Maretron addresses this head-on. The GPS200 automatically decodes correction signals from Satellite Based Augmentation Systems (SBAS), including the North American Wide Area Augmentation System (WAAS), the European EGNOS, and the Asian MSAS — delivering sub-3-meter positional accuracy in augmented conditions. An added benefit is the unit’s ability to broadcast precision magnetic variation data calculated using the vessel’s current position and the World Magnetic Model (WMM), a detail that matters greatly for autopilot accuracy.

Built for the Marine Environment

Maretron engineers its products to endure. The GPS200 features a compact, waterproof housing designed to withstand the harshest offshore conditions. It can be mounted on any standard 1"–14 threaded marine pole mount, flat-mounted to a deck surface, or — thanks to its high receiver sensitivity — even installed beneath a fiberglass deck. This mounting flexibility makes it practical for a wide range of vessel types, from center consoles to bluewater cruisers.
