5.2 Reference point of position

 The AIS stores one "external reference point" for the external GNSS antenna position and one "internal reference point" if an internal GNSS is to be used as fallback for position reporting. The locations of theses reference points have to be set during installation using values A, B, C, D; as described in paragraph 5.3.

The external reference point may also be a calculated common reference position.

Additionally, the content of the Ship Static Data ("SSD") sentence on the PI, including the "reference point for position" is being processed by the AIS, and the AIS' memory for the "external reference point" is set in accordance with the content of this "SSD" (e.g. used by an INS).
