A platform for autonomous survey operations on inland waterways and at nearshore coastal sites, capable of carrying larger sensors and small arrays. Can be launched and recovered with a two-man survey team, and is suited to survey campaigns in environmentally sensitive areas where the very quiet propulsion system eliminates disturbance. REAV-16 is also ideal for operations in shallow water, hazardous or spatially constrained areas – including close to channel edges or submerged obstructions.
