Sonardyne launches new navigation system for drones


Marine technology company Sonardyne has launched what it has described as “a top-of-the-line model” of its hybrid, underwater and surface navigation platform, SPRINT-Nav Mini.

According to Sonardyne, the new Navigator version expands the capabilities of the guidance model introduced last year, by calculating and providing the position of a remote, autonomous or manned underwater vehicle, or unmanned surface vessel, in addition to its speed, depth and attitude.

Small in size and low in power, SPRINT-Nav Mini is designed to provide precise, precise and robust guidance, as well as survey and inspection capabilities, for vehicle platforms that would not normally be in operation. able to accommodate high-end navigation systems. include observation class ROVs, low logistics AUVs, manned submersibles, swimmer delivery vehicles and USVs operating in shallow water, ”said Sonardyne.

Sonardyne says the Mini family combines an INS, AHRS, pressure transducer and 500 kHz DVL in a single underwater housing 215mm high, 149mm in diameter and 0.7kg in water. Sonardyne claims its solution is smaller, lighter, and less power hungry than any other competing technology in the same class, and less expensive than the individual vehicle sensors it replaces.

The solution is available in 300m and 4000m depth options, with a maximum DVL altitude of 200m. Existing SPRINT-Nav Minis owners can upgrade their guidance units to the new version of the Navigator, remotely in the field, the company said.

Aidan Thorn, Director of Business Development, Marine Robotics at Sonardyne, said: “These are incredibly exciting times for developers and operators of small ROVs, AUVs and USVs with transformative technologies such as our mini-navigator SPRINT- Nav which is a real catalyst for a safer and more efficient environment. , and cleaner operations across the sea.

He added, “The technology platform is low risk and field proven. This new flagship model will allow vehicle manufacturers and operators to reap all the benefits of inertial Doppler navigation from a single instrument. What I like is the simplicity, a unit that is simple to integrate and easy to use, leaving more space and power for other data collection payloads. And that ultimately means a more efficient vehicle for the user.
