Course gyro requirement
In order to operate correctly, the SY50 system requires input from a course gyro. A course gyro is not a part of the SY50 delivery. When a course gyro is connected to the SY50, the vessel’s current heading can be presented in the user interface.
Without the input from a course gyro, the SY50 system will not be able to present correct navigational information. In most cases a suitable course gyro is already installed on the vessel.
Note
Most global positioning system (GPS) can provide course information, but this data is generally too inconsistent to provide a stable presentation on the SY50 system. This inconsistency is especially noticeable at low vessel speeds. Incorrect course information can then result in settings not working properly.
We recommend that you use a satellite compass or a gyro compass.
