About SPRINT-Nav

SPRINT-Nav is Sonardyne's integrated acoustic-inertial navigation unit for ROVs, AUVs, USVs and other marine vehicles. A titanium housing combines a SPRINT inertial navigation system, Syrinx Doppler velocity log and pressure sensor, supplying position, altitude, depth, heading, velocity and motion data from one pre-calibrated instrument.

The I, S and X performance levels provide typical DVL-aided survey accuracy of 0.03%, 0.02% and 0.01%, with 4,000 m or 6,000 m depth-rated housings. Standard 625 kHz DVL configurations bottom-track to 175 m, while the 375 kHz high-altitude option reaches 230 m. The unit outputs data at up to 200 Hz and can add current profiling through an ADCP upgrade.

Timeline

MSubs and Sonardyne advance autonomous naval-platform capabilities
2022-03-08 - Partnership - The MoU covers integration and evaluation of Sonardyne’s navigation, communications and imaging payloads on MSubs’ 9 m extra-large uncrewed underwater vehicle. The named equipment includes SPRINT-Nav X for inertial-Doppler navigation, AvTrak 6 for long-range tracking and command and control, and Vigilant forward-looking obstacle-avoidance sonar. The partnership builds on a 2021 DASA UUV Testbed demonstration off Plymouth and targets future UK Ministry of Defence opportunities including Project CETUS.
