Vehicle drifts at the surface, continuously recording GPS signals. If enabled, it also estimates the evolving location of a surface drifter using the HFRCM components. Minimum height above the sea floor for the entire mission. 10.0 Maximum depth for the entire mission. 5.0 Minimum offshore distance for the entire mission. 2000.0 Elapsed time after previous surface communications when vehicle will begin to attempt additional surface communications. 12 Maximum length of mission 6 Buoyancy bladder position for drifting at the surface. This defaults to buoyancyLimitHiCC setting in the Config/Control.cfg file. Static setting for mass during the mission. This defaults to massDefault setting in the Config/Confrol.cfg file. 0 Safety behavior that keeps vehicle off sea floor Safety behavior that keeps vehicle from going too deep 0 Safety behavior that keeps vehicle away from the shore Initiate communications with shore. (Don't use Insert/NeedComms.xml here since that operates based on Universal:time_fix, which is continuously updated in this drift mission.) Note that there is a two-minute timeout on platform_communications, after which the mission will exit this aggregate. If communications are not completed, it will re-enter this aggregate immediately, take one GPS fix, and then try to communicate again. Record standard science data at the surface during the drift. Clean up any existing communications before starting to drift. HFRCMVSD.loadAtStartup: Reinitialized virtual drifter location to current vehicle location. Continuously query for GPS data.
