Explore with confidence
The ONWA KM series chartplotters are your ultimate companions for marine navigation. Designed to deliver reliability, speed, and advanced radar capabilities, the KM series ensures that you navigate the waters with the utmost confidence and precision.
Discover the next level of maritime navigation
When it comes to open-water navigation, the ONWA KM series chartplotters stand out as the ultimate choice for discerning mariners. With larger screen sizes, higher resolutions, and advanced features that surpass those of the KP series, the KM series is engineered to deliver a comprehensive, superior navigation experience.
Flexible connectivity
The KM series supports NMEA 0183, NMEA 2000, Wi-Fi, HDMI, and Ethernet connectivity, enabling seamless integration with other marine systems. This makes it easy to expand and customize your navigation setup.
User-friendly interface
The intuitive physical-button interface makes it easy to navigate the settings and features. Designed for ease of use, the KM series is accessible to both experienced mariners and those new to marine navigation.
Radar overlay on maps
The KM series enables the overlay of radar data on nautical charts, thereby combining visual navigational aids with real-time radar information. This feature enhances situational awareness by displaying radar echoes on the chart, making it easier to correlate radar returns with charted features.
Integrated AIS functions
- KM-8X and KM-8A, KM-12X and KM-12A: Built-in Class B+ AIS transponder (VHF antenna required)
- KM-8 and KM-8C, KM-12 and KM-12C: KS-200A and VHF antenna required
- Increased transmission rate (According to the speed)
- exactTrax™ : ExactTrax Tracking
AIS Message
- Can send and receive messages composed between ONWA AlS trackers.
- Messages can be broadcast or sent to a specific MMSi number.
- The message history and the number of unread messages can be viewed when a contact is selected.
- Pop-up box for incoming message alert
Chat sample
(Speaker icon displayed when the sent message is broadcast)
Discussion history
Can be viewed once a specific MMS is selected
CPA and TCPA alarm
Alarm that helps the user stay informed about nearby vessels by indicating the potential CPA and TCPA.
List of ships
Displays nearby vessels, their distance from your ship, and relevant information. By selecting a target from the list, you can view the vessel’s details.
SONAR SHARING AND RADAR SHARING
Radar functions are shared across ALL units in the network (the ONWA radar antenna must be connected to the KM-Router within the network). There is NO dedicated server or client for radar sharing; the KM-Router handles radar image distribution, and ALL units can control the radar antenna through the KM-Router.
