ComNav Marine Introduces G Series GNSS Satellite Compasses
ComNav Marine has launched its new G Series of GNSS satellite compasses, designed for reliable heading and positioning on recreational and commercial vessels. The series emphasizes redundancy, precise heading performance, and strong stability in roll, pitch and heading measurements—features that matter for navigation, autopilot control, and survey work at sea.
The G1 model delivers complete system redundancy and offers a high level of accuracy: heading performance is specified at better than 0.5 degree, while position accuracy is listed as less than 1 meter. These specifications are intended to provide dependable orientation and location information even in demanding maritime conditions. The G1 is priced at $2,340.
For operators who require additional options, the G2 and G2B variants extend the lineup and start at $2,645. ComNav also offers an optional G3 color display for those who prefer a local, graphical interface to view heading, position and status information directly at the helm or instrument station.
Key advantages of the G Series include built-in redundancy and improved stability of roll, tilt and heading outputs. Redundant design helps ensure continuous operation when precision and reliability are essential—particularly for vessels that depend on accurate heading for autopilot guidance, dynamic positioning, hydrographic surveying and other navigation-critical tasks. Enhanced roll and pitch stability contribute to smoother, more consistent heading information when a vessel encounters waves and motion, reducing the risk of erratic sensor readings.
Although compact and straightforward to install, GNSS satellite compasses such as those in ComNav’s G Series are beneficial across a range of marine applications. Recreational boaters gain confident course-keeping and better situational awareness, while commercial users—fisheries, workboats, and survey teams—can integrate reliable heading and position data into chart plotters, autopilots and data logging systems. The optional color display offers a user-friendly way to monitor system status without relying solely on an external multifunction display.
When evaluating a satellite compass for a vessel, consider factors such as redundancy, heading and position accuracy, integration capabilities with existing navigation systems, and ease of installation and use. ComNav’s G Series highlights redundancy and precise heading performance, making it a suitable option for operators who need a robust and dependable GNSS-based heading solution.
