Sonardyne Adds Flagship Navigator Model to SPRINT-Nav Mini Family

Energy, defence and science marine technology company, Sonardyne, has introduced a range-topping model of its hybrid, underwater and surface vehicle navigation platform, SPRINT-Nav Mini.

The new Navigator version, available to order from today, extends the capability of the Guidance model introduced last year, by calculating and providing the position of a remote, autonomous or piloted underwater vehicle, or uncrewed surface vehicle, in addition to its velocity, depth and attitude.

Small in size and low in power, SPRINT-Nav Mini is engineered to provide accurate, precise and robust guidance, and also survey and inspection capabilities, for vehicle platforms that would normally not be able to host high-end navigation systems. These include observation-class ROVs, low-logistic AUVs, manned submersibles, swimmer delivery vehicles and USVs operating in shallow waters.

With field-proven technology transferred from Sonardyne’s popular SPRINT-Nav product line, the Mini family combines an INS, AHRS, pressure sensor and 500 kHz DVL in a single subsea housing that is just 215 mm-high, 149 mm in diameter and as little as 0.7 kg in water; smaller, lighter and lower power than any other competing technology in the same class, and lower in cost than the individual vehicle sensors it replaces.

SPRINT-Nav Mini continues to work even in challenging environments, such as around surface structures and GNSS denied environments, providing a continuous stream of latitude and longitudes, orientation, velocities, depth and altitude at up to 200 updates per second to a vehicle’s primary control system.

Available in 300 m and 4,000 m depth options, with a class leading maximum DVL altitude of up to 200 m, all SPRINT-Navs are supplied pre-calibrated from the factory, enabling users to install it and get to work easily and quickly. Existing owners of SPRINT-Nav Minis can upgrade their Guidance units to the new Navigator version, remotely in the field.
