IXSEA presents RAMSES, the intelligent embedded positioning

IXSEA presents RAMSES, the intelligent embedded positioningIXSEA will present its new product, RAMSES, at 0i08, which takes place from 11 to 13 March 2008 at ExCeL, London, the company announced today (Friday).

RAMSES is a unique positioning system which combines an embedded data fusion engine, real-time range and positioning computation, USBL acoustic positioning data as well as coupling with PHINS Inertial Navigation System.

RAMSESRAMSES' operating principle, Simultaneous Localization And Mapping (SLAM), was developed in the 80s as a technique used by robots to position themselves while building up a map within an unknown environment. RAMSES uses SLAM to compute the unknown positions of beacons deployed on the seabed while keeping track of its own current location and to provide on-the-fly array calibration. When RAMSES is aided by an external subsea positioning system (INS or USBL), SLAM can be operated with only one transponder and delivers unique sparse array operating capacity.

RAMSES works in an open and flexible way and can be either used in stand alone mode or combined with other positioning systems to improve overall performance. In stand alone mode, RAMSES can be used on small Autonomous Underwater Vehicles (AUV) and small Remotely Operated Vehicles (ROV). When combined with PHINS Inertial Navigation System, applications include: AUV long-term navigation such as pipe survey; accurate seabed imagery survey; AUV defense applications with deployed transponders not previously calibrated and ROVs. When coupled with PHINS Inertial Navigation System plus GAPS (IXSEA’s calibration free USBL) or any other high-grade USBL, it can be used for ROV inspection, maintenance and repair as well as subsea construction.

"RAMSES, the intelligent embedded positioning system, is definitely a technological breakthrough which works in either stand alone mode or in combination with IXSEA's other systems," said RAMSES Product Line Manager, François Crétollier.
