Mission Flight Test Data Results Gliders vs. Other Monitoring Means Gliders Potentials

Pre Launch

 Pre-Launch Operation • Flight Plan and Navigation • Depth and Dive Angle • Samples Collecting Profiles • Glides Components Test • Emergency RF Beacon Tested • Drop Weight • Hydraulic System • Compas • GPS • CTD

Launch



Launch Operation

• Ambillical Cord disconnected • Glider lowered into the water • First Dive Test • Receiving first E-mail • Sending away

Typical Mission Flight

• Glider is Programmed • Glider is Tested on board of ship • Glider is lowered into the water • Starboard wing is raised for GPS • Port wing is raised for Iridium • Starboard wing is raised again for GPS • Pitch battery moves forward • Oil is being transferred into the int. Bldr • First dive initiated

Cont.

• First dive 50 meters • On the surface repeats the wing rolling • Ready to start the mission • Total time spent at the surface:10-15 m
