SPRINT-Nav is an all-in-one subsea navigation instrument for underwater vehicles. It combines Sonardyne’s SPRINT INS, Syrinx DVL (Doppler Velocity Log) and high accuracy intelligent pressure sensor in a single housing that is one of the smallest combined inertial navigation instruments on the market.

SPRINT-Nav is available in three different performance levels; 300, 500 and 700, and two different depth ratings; 4,000 and 6,000 metres. It offers two DVL frequencies; 600 kHz and a high-altitude 400 kHz option.

The unit is comprised of three high grade Ring Laser Gyros (RLG) and accelerometers. These ultra-reliable sensors are used also for safety critical navigation by the majority of the world’s large commercial aircraft and do not require factory recalibration over the product’s lifespan.
