Sonardyne’s SPRINT-Nav reaches new heights of capability

Marine technology specialist Sonardyne has released a new high altitude variant of its market leading hybrid navigator SPRINT-Nav to allow uncrewed surface vessels (USVs) and underwater vehicles to extend their operational envelope.

SPRINT-Nav tightly integrates a Sonardyne SPRINT INS, Syrinx DVL and a highly accurate pressure sensor into a single high-performance solution providing navigation and optional acoustic Doppler current profile (ADCP) functionality. Sonardyne’s new variant takes this capability to an even higher level; increasing the altitude at which vehicle platforms can work when they don’t have an external position reference, without compromising accuracy.

Operating at 400 kHz, the high altitude variant achieves reliable bottom lock at up to 230 m altitude above the seabed, providing USVs with a highly accurate and robust navigation source, which is critical for, as an example, station keeping applications in coastal surveys where GNSS could be denied or subject to interreference. Installation of the new SPRINT-Nav variant on autonomous underwater vehicles (AUVs) and remotely operated vehicles (ROVs) allows inspections and surveys to be performed at even higher altitudes than previously possible. In addition, the instrument’s optional ADCP functionality has been extended to 120 m, adding oceanographic data gathering and increased operational capability.
