How to verify correct datum used in positioning
It is very important that output co-ordinates of position device is the same as the ECDIS expects to receive,
otherwise there is a risk that you have incorrect position in the ECDIS. Verify in position device configurations that
output of co-ordinates is WGS84 and also in installation parameters in the ECDIS is set to receive position in
WGS84 datum.
