SPRINT-Nav is a compact, all-in-one navigation instrument combining inertial, Doppler, and depth sensing in a single titanium-housed unit. Designed for AUVs, ROVs, USVs, and XLUUVs, it merges SPRINT INS, Syrinx DVL, and a high-accuracy pressure sensor to deliver precise position, velocity, and attitude data in real time. The system supports autonomous and crewed missions across deep and shallow water environments, offering calibration-free deployment and pre-aligned sensors for immediate operational use. Its integration of multiple navigation sources improves positional stability, enabling high-precision station keeping, survey operations, and autonomous control.
Available in four performance levels (300, 500, 700, and X) and two DVL frequency options (400 kHz for high-altitude and 600 kHz for high-resolution tasks), SPRINT-Nav adapts to a wide range of mission requirements. The X model achieves exceptional accuracy under 0.01% of distance traveled, making it ideal for long-endurance operations in defense, science, and offshore energy sectors. Features include dual algorithms for piloting and survey modes, individually replaceable DVL transducers, and onboard data storage with power-pass-through design to minimize cabling. Compact, robust, and precise, SPRINT-Nav simplifies navigation integration while maximizing mission reliability.
