SPRINT-Nav Mini is the world’s smallest hybrid acoustic-inertial navigator. An all-in-one subsea navigation instrument with performance beyond its size. It replaces separate AHRS, DVL and depth sensors. Less cabling. Fewer connectors. Simpler to mobilise. SPRINT-Nav Mini, like all instruments in the SPRINT-Nav family, is more than the sum of its parts.

Measuring in 215 mm in height, 149 mm in diameter and weighing in at approximately 3.6 kg in air – or 7.1 kg for the 4000 m depth version – for something so small, SPRINT-Nav Mini packs a big punch for observation-class, electric and drill support work-class ROVs. Use it also in support of unmanned systems working in GPS denied environments, as well as towfish, diver swim-boards and swimmer delivery vehicles.

SPRINT-Nav Mini is powered by the same hybrid acoustic-inertial navigation algorithm you’ll find inside our established SPRINT-Nav family. This combines the strengths of all the sensors contained within to provide robust, precise and accurate outputs. It continues to work even in challenging environments and provides a continuous stream of orientation, velocities, depth and altitude at up to 200 updates per second.

SPRINT-Nav Mini arrives pre-calibrated from the factory, meaning there is no need to manoeuvre your vehicle every time the unit is mobilised. SPRINT-Nav Mini does the thinking for you, all in a single plug-and-play unit. Turn it on, give it a latitude, and away you go. However, despite its extremely small size, it’s still a true north seeking gyrocompass which won’t drift over time unlike MEMS-based systems. The output can be fed directly to your own (or a third party) user interface or vehicle control software. The simple Web User Interface makes set up and configuration painless. It could not be any simpler.
