Simrad TPR datagram format

Simrad TPR is a proprietary datagram format created by Kongsberg Maritime. It provides the relative bearing and water depth of the trawl sensor, as well as its distance from the vessel. The bearing resolution is 1 degree.

Format

@IITPR,x,M,y,P,z.z,M<CR><LF>

Description

Note

All data relate to the trawl sensor (target).

II: Talker identifier

TPR: Datagram identifier

x,M: Horizontal range (Metres) (0 – 4000 )

y,P: Bearing in degrees (Relative to vessel heading)

z,z,M: Depth (Metres) (0 – 2000 )

Note

The Simrad ITI measures the depth differently from the range and the bearing. If the ITI only knows the range and the bearing, the depth field is empty.
