Completing the Gaps Series, iXblue Posidonia is an ultra-short baseline (USBL) acoustic positioning system dedicated to the highly accurate and ultra–long range tracking of subsea vehicles beyond 10,000 m.

A tailor-made system for every operation

The Posidonia USBL system is available in two versions to meet operators’ diverse needs. Offering operational flexibility, its deployable version can be used from a side pole, moon pole or from a hoisting system deployment.

Posidonia flush version offers an efficient USBL that can be permanently installed on the hull of a ship, without the need to deploy it for every operation. This incidentally allows fast navigation, even while operating the USBL positioning system.

A pre-calibrated version is also available to operators who need an all-in-one solution that combines a USBL antenna with a motion sensor (both iXblue or third-party), for easy and fast deployment.

A high-performance ultra-long-range USBL

With an operating range reaching over 11km, Posidonia offers extremely long-range accuracy. Increased performance can further be achieved by mechanically coupling Posidonia with an iXblue Phins INS or Octans subsea AHRS before delivery, for a ready to operate solution. iXblue USBL can also be coupled to third-party gyroscope if needed.

DP compatibility

Just like the Gaps Series, the Posidonia USBL is compatible with all major Dynamic Positioning (DP) Systems used within the industry. Its ultra-long range will ensure operators get the highest accuracy even in the most noisy and challenging environments, making it the perfect tool for Oil&Gas operations.

Addressing diverse applications

The Posidonia ultra-long range USBL system is the perfect fit for many applications within the Oil&Gas and Science industries.
