Simrad GLL datagram format
Simrad GLL is a proprietary datagram format created by Kongsberg Maritime to provide
the current geographical position of the trawl sensor.
Note
The GLL datagram may be received from integrated instruments using the “ii” talker
identifier. The Simrad ITI system uses the same talker identifier “ii”, and this has caused
some confusion. In order to rectify this, the ITI GLL datagram has been inhibited.
