Mission ID: PAM

Mission Path: Engineering/passive_acoustic_monitoring.tl

The mission will dive LRAUV to the start/center depth, then hold the vehicle at neutral buoyancy/trim with all actuators disengaged. The science payload will be powered.

Arguments

MissionTimeout

MissionTimeout = 180 minute

Maximum duration of mission

AcousticTrackingTimeout

AcousticTrackingTimeout = 240 hour

If the vehicle does not receive an acoustic signal for more than this length of time, it will surface for communications. Set longer than MissionTimeout to effectively disable.

SurfacingIntervalDuringListening

SurfacingIntervalDuringListening = 180 minute

When the listening depth bound is breached and the submergence time has surpassed SurfacingIntervalDuringListening, the vehicle will surface.

NeedCommsMaxWait

NeedCommsMaxWait = 180 minute

If the submergence time has surpassed NeedCommsMaxWait, the vehicle must surface, to caution against drifting too close to shore during submergence. Can set it to a huge number to effectively disable it.

How often to surface for commumications during transit.
