MFDs running LH II or LH 3 software - Overlaying chart with radar using COG reference

MFDs running LH II or LH 3 software - Overlaying chart with radar using COG reference
MFDs running LightHouse II or LightHouse 3 software - Overlaying chart with radar using COG reference

When operating with the latest LightHouse 2 or LightHouse 3 software, a/c/e/eS/gS-Series MFDs Axiom & Axiom Pro MFDs will support the overlaying cartography with radar within Chart application using heading data or COG. However, as a stationary vessel has no COG, MFDs which have not been interfaced to a source of heading data will be unable to overlay cartography with radar when the vessel is stationary. In the absence of a source of heading data, once underway and making way and having acquired a GPS position FIX, then the Chart application will permit cartography to be overlaid with radar.

Should one desire to use the MFD's MARPA radar features, then a heading sensor supporting 10Hz or greater heading updates is recommended (ex. Raymarine EV-1 Sensor Core, Airmar H2183, KVH AutoComp 1000, etc.). Raymarine's EV-1 Sensor Core has the advantage of being similarly priced to the other sensor alternatives and is a core component of an Evolution autopilot. As such, should the system ever be expanded to include an autopilot, then the EV-1 Sensor Core could be removed from the list of required autopilot components.

Raymarine recommends that accurate 10Hz or greater heading data be supplied to any system using using any of (but not limited to) the following Radar and Chart application features:
- MARPA
- AIS Targets Displayed within the Radar Application
- Waypoints Displayed within the Radar Application
- North Up or Course Up orientiation within the Radar Application
- Radar Overlay within the Chart Application .. may be used with COG alone ... requires that the vessel be underway and making way.
- Heading Vector within the Chart Application
- Vessel Icon Orientation within the Chart Application (will default to COG when no heading data source is detected)
- Chart Orientation within the Chart Application (will default to COG when no heading data source is detected ... when not moving or operating at maneuvering speeds, the Chart orientation will revert to North Up unless the system is interfaced to a source of heading data)
- Heading Databar / Sidebar, Data application, and Databox/Data Overlay data items
- Relative bearings within AIS Target List
- Other heading dependent features.
