Chartplotter KP-39A/ONWA
Onwa KR-39A chartplotter from Onwa Marine is a universal device for ensuring navigation safety of various types of vessels. Onwa KR-39A chartplotter displays the location of a watercraft on electronic maps. It also allows exchanging navigation and other data with other vessels and coastal services. The device memory can store route data in both directions. The 7-inch color LCD plotter has a built-in AIS transponder class B+, GPS antenna. AIS is equipped with a VHF transmitter, two TDMA receivers of two VHF channels, an interface, a communication processor, and a GPS receiver. The latter allows providing data on the vessel’s position, COG, SOG. The device memory can store 12,000 user waypoints, up to 30 routes.
