Installation was surprisingly simple, primarily involving running the cable to the T122 Wireless NMEA Interface and mounting the sensor itself. I chose an interior mounting location, just below the deckhead, to shield it from direct weather, a testament to its flexibility as described. The unit’s small form factor made finding a suitable, unobtrusive spot incredibly easy. The Micronet system, already configured and operational, recognized the new data source almost immediately after power-up. There was a slight delay as the sensor acquired its first satellite fix, which is standard for most GPS units, but once it locked on, the Course and SOG data began populating on my existing display. No complex calibration or setup menus were required, which was a refreshing change from some other electronic installations I’ve undertaken.

Extended Use & Reliability

After several weeks of consistent use, encompassing day sails, longer coastal passages, and periods of inactivity, the Raymarine Active GPS Sensor has proven its worth. It reliably provides accurate positional data, and the SOG and Course Over Ground (COG) readings remain stable and consistent, even in areas with partial sky obstruction from surrounding buildings or other vessels. I haven’t noticed any degradation in performance, nor have I had to recalibrate or reset the unit. Maintenance has been non-existent beyond a quick wipe-down during general boat cleaning; there are no moving parts to worry about, and the sealed unit seems well-protected against the occasional spray or damp environment within the boat’s cabin. Compared to previous GPS antennas I’ve used that were prone to signal drift or required frequent reboots, this Raymarine sensor feels like a significant step up in terms of dependable, set-and-forget performance. It’s performed admirably, integrating seamlessly into the existing Micronet network.

Breaking Down the Features of Raymarine Active GPS Sensor f/Micronet System

Specifications

The Raymarine Active GPS Sensor f/Micronet System is a compact, lightweight device, weighing in at a mere 108 grams without its cable. It boasts 16 parallel channels, a standard for modern GPS receivers, which ensures a good number of satellites can be tracked simultaneously for improved accuracy and faster acquisition times. The specified accuracy of 3.3m RMS (DOP) is perfectly adequate for general navigation and positioning needs on a sailboat. Its physical dimensions are also noteworthy, with a mounting profile of 22mm (Diameter) x 15mm (Height) for the bolt, allowing for discreet installation. The unit comes equipped with a standard (1″x14) pole mount adapter, offering versatility for deck, mast, or stanchion mounting, although I opted for an internal mount. This small form factor and simple installation process are key selling points, making it an easy addition to an existing Micronet setup.

Performance & Functionality

The primary function of the Raymarine Active GPS Sensor f/Micronet System is to inject critical GPS data into the Micronet system, and it performs this role admirably. The accuracy of position fixes is consistent, providing a reliable anchor for navigation. The Course Over Ground and Speed Over Ground data are smooth and responsive, updating frequently enough to be useful for real-time decision-making while sailing. I found the data to be robust, with minimal dropouts even when passing close to larger structures that can sometimes interfere with GPS signals. Its core competency lies in its seamless integration; the sensor does exactly what it’s designed to do without fuss, and the data it provides is precise for its intended application. It doesn’t offer advanced features like WAAS/EGNOS correction, but for the intended purpose of augmenting a Micronet system, its performance is strong and reliable.

Design & Ergonomics

The design of this GPS sensor is a clear win for practicality and marine environments. Its small form factor is a significant advantage, allowing for installation in tight spaces where larger antennas might not fit. The black casing is understated and blends well with marine equipment.
