7.10 Heading sensor requirements
The heading sensor can be a stand-alone unit or may be integrated into an auto-pilot system,
provided that it supplies the NMEA 0183 HDG, HDT, OSD, HCC, HCD or HDM heading sentences
to the navigator. It must output data at a 10 Hz update rate.
If the heading sensor requires sea trial calibration, perform the manufacturer's recommended
calibration procedure before you calibrate the radar heading.
Heading calibration should be performed during initial setup, annually, and after any major
structural changes to the vessel.
The Northstar 6000i and 6100i accepts the following standard NMEA 0183 sentences from a
heading sensor (such as the Simrad RC37 Rate compass) to obtain the following heading
information: HDG, HDT, OSD, HCC, HCD, and HDM.
For sensor installation and calibration instructions, see the sensor manufacturer's Installation
Manual. In addition, the navigator must be calibrated to the
heading sensor
(see "Set the
heading calibration (heading sensor installed)" page 53) and, for a 6000i or 6100i system
installation also see "GM6KIM Rev D (6000i Installation Manual)" or the new "MN000320A
Northstar 6000i & 6100i Installation Manual"
7.11 Disable the heading sensor input
The heading sensor is configured by default when the navigator is configured for radar.
If a heading sensor is NOT installed and connected, you must remove its configuration as
follows:
•
Turn on the navigator and wait for it to complete its power-up sequence.
•
Press RADAR to display the radar screen on the 6000i or 6100i.
•
The system asks if you want to turn on the scanner. Press Enter to turn it on.
•
Press Page 2 , Page 3 , Page 4 , and Install... to show the installation screen.
• Press Hdg Sensor Installed to change its displayed status to No .
• Press STAR to display the alarm screen, then press Clear Alarm . This clears the heading
sensor alarm.
7.12 Calibrating the radar
You must calibrate the newly installed radar by adjusting the trigger delay and the heading
calibration.
To evaluate medium and short range returns, you are recommended to perform the calibration
at sea in a normal operating environment and under fair weather conditions. There should be
an area of at least 3 nautical miles forward of the vessel, containing known targets including the
coastline. A wave height of about one to two feet (half a meter) to create some sea clutter, is
ideal. Do not perform the calibration in an enclosed or busy area such as a boatyard.
Attempts to tune and calibrate under less than recommended conditions may lead to
substandard performance. A sea trial that allows the selection and use of all the ranges is highly
desirable.
7.13 Prepare for calibration
Prepare for calibration as follows:
•
Press RADAR to display the radar screen on the 6000i or 6100i.
• The unit may ask if you want to turn on the scanner. If it does, turn it on. You should
see range rings displayed on the screen or the scanner warm-up countdown followed by a
message saying "Radar is OFF". If nothing appears, the radar control box is not powered
up or not properly interfaced to the navigator. Check the power wiring, interface wiring,
and navigator communications configuration.
