Operation In Gyro-Free Mode - Furuno FV-110GX Operator's Manual

4. Type the user name admin (default) and the password iDirect (default).
5. In the menu Commissioning click One Touch Commissioning.
6. Click Start. One Touch Commissioning takes place. When commissioning is
completed the antenna will search for the I5 satellite with the highest elevation.
7. The antenna will find the satellite and the modem will perform the necessary steps to
enter the network (software upgrades, if available).
8. The web interface of the iDirect core module will indicate the modem in the network
as well as the modem status in the display in the menu MODEM of the FV-110GX
web interface.
9. When commissioning is completed, test all subscribed services.

Operation in gyro-free mode

If input from a gyro compass is not available (Heading input: none), information from the
GPS position is used when searching for a satellite. If the antenna does not have ship
heading input from the vessel's gyro compass, the azimuth direction of the satellite is not
known. In this case the antenna will start a 360 degrees sky scan and scan until it finds a
satellite. The search time to find the satellite and start tracking is therefore increased
considerably. If the ship is on a steady course and sails at a speed over ground above 5 kn,
the system can use an estimated heading from the current GPS position. This will reduce
the search time, but it will still be a longer search time than with heading input present.
If the system loses the signal from the satellite, for example due to blockage, and the
duration of signal loss is longer than approximately 1 minute, the system without heading
input must do a new sky scan to find the satellite when the antenna is out of blockage.
