Sonardyne’s SPRINT-Nav inertial navigation system (INS) has been selected by the UK’s National Oceanography Centre (NOC) for its under-ice Autosub2KUI (A2KUI) AUV, the company announced on 10 April.

A2KUI is a 2,000m depth-rated AUV specifically designed for carrying high-performance sensors on challenging research missions under polar ice.  

The SPRINT-Nav 700, selected by the NOC, is equipped with high performing sensors, including Honeywell ring laser gyros and accelerometers. It combines Sonardyne’s SPRINT INS sensor, Syrinx 600 kHz Doppler Velocity Log and a high accuracy intelligent pressure sensor into a single housing. SPRINT-Nav’s tight integration of all the raw sensor data at a low level provides better navigational performance and precision for subsea vehicles.

A2KUI will also be equipped for acoustic tracking using Sonardyne’s Ranger 2 Ultra-Short BaseLine system, which is fitted to the UK research vessels RRS James Cook, RRS Discovery and the new polar research vessel RRS Sir David Attenborough.
