Before initialisation the approximate latitude and longitude message will have the GNSS measurement of
latitude and longitude (at the GNSS antenna location). After initialisation it will contain the same latitude
and longitude as message 601h.

By default, the altitude is output relative to mean sea level, not WGS 84. See altitude in the NCOM
description for information on how to change this. Before initialisation the approximate altitude message
will have the GNSS measurement of altitude (at the GNSS antenna location). After initialisation it will
contain the same altitude as message 602h.
