A former OceanGate contractor, Antonella Wilby, testified before a U.S. Coast Guard panel on Friday that the company’s Titan submarine, which imploded last year during a dive to the Titanic’s wreckage, relied on an incredibly convoluted navigation system.
As Wilby described it during the US Coast Guard Marine Board of Investigation hearing, the Titan’s GPS-like ultra-short baseline (USBL) acoustic positioning system generated data on a sub’s velocity, depth, and position using sound pings.
