Next on our list of must-sees this year is Digital Yacht’s new GPS150 DualNav GPS Sensor. It combines a 50-channel GPS with GLONASS, the Russian-funded satellite system that is now online. The smart sensor inside the GPS150 will automatically switch between the systems, depending on which is available, or you can make a manual choice. When the European-funded Galileo positioning system comes online in 2018, the GPS150 will work with that, too. Learn more at www.dualnav.com.
