Sonardyne underwater technologies support DARPA-funded AUV programme.

US-based underwater robotics developer Dive Technologies has chosen a complete suite of Sonardyne navigation, tracking and control technologies for its large-displacement DIVE-LD AUV programme.

DIVE-LD AUV is intended to meet a wide range of long-endurance mission requirements, across the commercial, research and defence sectors. To support long-distance and long-duration navigation, while minimising complexity and payload space consumption, the vehicle is fitted with the SPRINT-Nav hybrid navigator from Sonardyne.

For underwater positioning and acoustic communications, the DIVE-LD is fitted with the Sonardyne AvTrak 6 – a combined transponder, modem and emergency relocator beacon. To cover all CONOPS, including tracking and communication during development and testing, Dive Technologies has also acquired the Ranger 2 ultra-short baseline system.

DIVE-LD is 48in (1.22m) wide and 19ft (5.79m) long, designed for operations at depths down to 6,000m. The AUV is under in production in the US, with sea testing ongoing in New Bedford.
