SPRINT-Nav is an all-in-one subsea navigation instrument for underwater vehicles. It combines Sonardyne’s SPRINT INS sensor, Syrinx 600 kHz Doppler Velocity Log (DVL) 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 two different performance levels; 300 and 500, and two different depth ratings; 4,000 and 6,000 metres.
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.
