$PTSAL,xxx.x,xxx.x,yyy.y,yyy.y,zzz.z,zzz.z*hh<cr><lf>
•
$PTSAL: talker identifier + sentence formatter
•
xxx.x: horizontal range in meters to sensor 1
•
xxx.x: horizontal range in meters to sensor 2
•
yyy.y: bearing to sensor 1 relative to stern line
•
yyy.y: bearing to sensor 2 relative to stern line
•
zzz.z: depth in meters of sensor 1
•
zzz.z: depth in meters of sensor 2
•
*hh: checksum
$PMPT,POS,aa,xxxx.x,M,yyy.y,T,zzz.z,M,ddd.d,M,hhmmss*<chk><cr><lf>
•
$PMPT: talker identifier + 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).
•
xxxx.x: horizontal distance in meters
•
yyy.y: true bearing (deg.rel.north) to sensor
•
zzz.z: depth below surface distance in meters
•
ddd.d: distance to bottom in meters if available, or empty
•
hhmmss: time of data (hour-minutes-seconds)
•
*hh: checksum
@IITPT,xxxx,M,yyy,P,zzzz.z,M<cr><lf>
•
@IITPT: talker identifier + sentence formatter. (TPT = Trawl position true vessel)
•
xxxx,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.
•
yyy,P: true bearing to the target (i.e. relative to north). Requires gyro input for reliable data.
•
zzzz.z,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
