Watch the REGENT seaglider 'dangle test' to calibrate the vessel's sensors

The REGENT team conducts a "dangle test" of the Viceroy seaglider prototype to calibrate the sensors on the vessel that accurately measure the distance between the seaglider and the sea's surface. This test is part of a months-long sea trial campaign to test the full-scale seaglider prototype and prepare for the first human flight.
