Mission Path: Engineering/tritoncam_transect.tl

Transect mission for Triton LRAUV.

Companion frontseat mission for the adaptive backseat running the transect strategy. While searching, the vehicle yo-yos within the backseat-supplied depth band and transits the waypoint list. When the backseat detects a target it HOCKEY-STOPS and runs a TRANSECT leg: the strategy COLLAPSES the yoyo band to the detection depth (publishes .YoYoMinDepth == .YoYoMaxDepth) and drives _.speed_command (negative during the hockey stop, positive during the leg).

This mission uses that collapsed band as the "hold depth / run the leg" signal: the DepthEnvelope+YoYo hold the detection depth, and Guidance:Point applies a transect rudder to sweep the hotspot. It resumes yoyo/transit when the backseat re-opens the band. The rudder magnitude lives HERE (frontseat), so no backseat variable beyond the ones circle_hotspot already uses is required.

Arguments

MissionTimeout

MissionTimeout = 500 hour

Maximum duration of mission

NeedCommsTime

NeedCommsTime = 100 hour

How often to surface for communications

MinDepth

MinDepth = 10 meter

Minimum depth of the yoyo envelope. Updated by backseat via _.YoYoMinDepth. Collapses to the detection depth (== MaxDepth) during the transect leg.

MaxDepth

MaxDepth = 60 meter

Maximum depth of the yoyo envelope. Updated by backseat via _.YoYoMaxDepth. Collapses to the detection depth (== MinDepth) during the transect leg.

Speed

Speed = 1 meter_per_second

Vehicle speed. Updated by backseat via _.speed_command (negative during the hockey stop, positive during the transect leg).

YoYoDownPitch

YoYoDownPitch = -15 degree

Vehicle pitch while diving (negative = nose down).

YoYoUpPitch

YoYoUpPitch = 15 degree

Vehicle pitch while climbing (positive = nose up).

TransectRudder

TransectRudder = 15 degree

Rudder angle applied during the transect leg (and hockey stop). The turn magnitude is decided here on the frontseat, not by the backseat.

TransectBandThreshold

TransectBandThreshold = 1 meter

The yoyo band is treated as "collapsed" (transect / depth-hold mode) when MaxDepth - MinDepth is below this. The backseat collapses the band to the detection depth to request the leg.

TransectCheckInterval

TransectCheckInterval = 15 second

How often, while running the leg, to re-check whether the backseat still wants it (i.e. whether the band is still collapsed). The leg breaks out as soon as the backseat re-opens the band.

StateUpdateDelay

StateUpdateDelay = 1 second

Minimum time delay between state updates to avoid rapid changes.

MinAltitude

MinAltitude = 5 meter

MaxSafeDepth

MaxSafeDepth = 100 meter

MinOffshore

MinOffshore = 1.5 kilometer

Repeat

Repeat = 10 count

Number of times to cycle through the waypoint list.

Lat2

Lat2 = NaN degree

Latitude of waypoint 2. NaN entries are skipped. The vehicle yo-yos while transiting to each waypoint, so at least one is required.

Lon2

Lon2 = NaN degree

Longitude of waypoint 2. NaN entries are skipped.

Lat3

Lat3 = NaN degree

Latitude of waypoint 3. NaN entries are skipped. The vehicle yo-yos while transiting to each waypoint, so at least one is required.

Lon3

Lon3 = NaN degree

Longitude of waypoint 3. NaN entries are skipped.

Lat4

Lat4 = NaN degree

Latitude of waypoint 4. NaN entries are skipped. The vehicle yo-yos while transiting to each waypoint, so at least one is required.

Lon4

Lon4 = NaN degree

Longitude of waypoint 4. NaN entries are skipped.

Lat5

Lat5 = NaN degree

Latitude of waypoint 5. NaN entries are skipped. The vehicle yo-yos while transiting to each waypoint, so at least one is required.

Lon5

Lon5 = NaN degree

Longitude of waypoint 5. NaN entries are skipped.

Lat6

Lat6 = NaN degree

Latitude of waypoint 6. NaN entries are skipped. The vehicle yo-yos while transiting to each waypoint, so at least one is required.

Lon6

Lon6 = NaN degree

Longitude of waypoint 6. NaN entries are skipped.

Lat7

Lat7 = NaN degree

Latitude of waypoint 7. NaN entries are skipped. The vehicle yo-yos while transiting to each waypoint, so at least one is required.

Lon7

Lon7 = NaN degree

Longitude of waypoint 7. NaN entries are skipped.

MassHold

MassHold = true

Set to True to hold mass at default position.
