Doppler data source requirements
Use of the Doppler Radar features requires the following data sources to be available on your system
(e.g. connected to your multifunction display, via SeaTalkng ® or NMEA 0183).
Required data sources
Data type
Example data source
COG (Course Over Ground)
GPS or GNSS receiver (MFD internal receiver or
external receiver).
SOG (Speed Over Ground)
GPS or GNSS receiver (MFD internal receiver or
external receiver).
Recommended data source
Data type
Example data source
HDG / HDT (True Heading)
Compass or Autopilot sensor providing
Fastheading data (e.g. Evolution EV-1 / EV-2).
Note:
A Heading data source is not essential for Doppler operation. However it will improve the
performance of Doppler mode at slower speeds (< 15 knots), when tide set and leeway are present.
12.12 Blank sectors
Blank sectors can be manually set to hide sections of your radar display. This is useful for vessels
that experience false radar readings from onboard structures or equipment.
Note:
Sector blanking is only compatible with Magnum Open Array radar scanners.
Blank sectors can be enabled from the Radar app settings:
Radar app > Settings menu > Installation
Two blank sectors can be enabled. You can edit the minimum and maximum limits of each blank
sector; this will determine how much of the radar display is hidden.
Blank sectors can be enabled / disabled on the radar overlay in the Chart app:
Chart app > Settings
menu > Radar settings
