Configuring a Radar with Asterix Protocol Support
Important
The description of the radar image source configuration is of a general nature.
For correct operation of the radar image source, configuration must be performed by a specialist with the appropriate technical knowledge and skills who has completed training with the ECDIS manufacturer.
Warning
Incorrect configuration of the radar image source may result in incorrect display of the radar image on the chart and an erroneous assessment of the navigational situation.

Parameter |
Description |

Radar antenna position |
Radar antenna coordinates relative to CCRP |

Range Adjustment |
Range correction. Determination and compensation of the range correction is performed using a distant point object |
3 |
Bearing Adjustment |
Bearing correction. Determination and compensation of the correction is performed using a distant point reference |
Important
Incorrect antenna position alignment causes displacement of the radar image relative to the chart, which may create a dangerous navigational situation. Alignment verification and correction must be performed:
During initial configuration of the radar image source
Before each voyage departure
After repair work on the radar antenna
When systematic discrepancies between the radar image and chart information are detected
At least once a month during operation
Blank sector
When operating with a Radar, the Blank sector activates sectors within which the antenna’s high-power transmission is disabled.

Note
If the equipment (radar) does not support Blank sector configuration from external devices, the sectors can be used to mask interference sectors. In this case, during primary signal processing, the specified sectors are excluded from processing and display.
