$PMPT,POS,AA,bbb.b,M,ccc.c,T, ddd.d,M,eee.e,M,hhmmss*<chk><cr><lf>
• $PMPT : talker iden sentence formatter
• POS : position
• AA : 2 letters code that specifies the part of the gear (SD = starboard door / PD = port door / CL =
clump on twin trawl / SC = starboard clump on triple trawl / PC = Port Clump on triple trawl).
•
bbb.b,M : horizontal distance in meters
• ccc.c,T : true bearing (deg.rel.north) to sensor
• ddd.d,M : depth below surface distance in meters
• eee.e,M : distance to bottom in meters if available, or empty
• hhmmss : time of data (hour-minutes-seconds)
• *hh : checksum
@IITPT,aaa,M,bbb,P,ccc.c,M<cr><lf>
• @IITPT : talker iden sentence formatter. (TPT = Trawl position true vessel)
• aaa,M : horizontal range in meters to the target (0 - 4000 m). Requires an active depth sensor on
the trawl or manual set depth, if not the slant range will be presented.
• bbb,P : true bearing to the target (i.e. relative to north). Requires gyro input for reliable data.
• ccc.c,M is the depth in meters of trawl below the surface (0 -2000 m). Requires an active depth
sensor on the trawl or manual set depth, if not the depth field will be empty
