A new version of the successful Orion INS (Inertial Navigation System) was launched by Teledyne TSS Ltd at Europort in Novemeber. The OrionPLUS aims to meet the needs of marine users and those in the hydrographic survey, offshore subsea construction and ROV (Remotely Operated Vehicle) operating industries who need a dependable and competitively priced reference system. It can provide precise attitude, heading and heave data and is suitable for a wide range of applications such as supporting multi-beam sonar surveys or the construction of major seabed installations.
Customers are also expected to welcome the convenience that comes from the ability of OrionPLUS to process log speed from several different types of instrument using NMEA 0183 VBW.
Heave data is available with the OrionPLUS and are accurate to 5 cm or 5 per cent over ranges to 99 metres. The performance of the Orion's components and software means that users will benefit from headings accurate to 0.1º sec lat, roll and pitch measurements to within 0.005º through a range of ± 90°.
The OrionPLUS incorporates the many years of technical expertise in motion sensor technology achieved by the Watford, UK- based company. Dependability has been built-in by Teledyne TSS with the painstaking selection of components and software developed to meet the demands and expectations of its users.
The software and algorithms used have been refined over many years by Teledyne TSS and they process data generated by three ring laser gyros (RLG) and accelerometers chosen for their dependability and accuracy. They can be used at operating temperatures ranging from -15°C to +55°C and require a settling time of less than 15 minutes (in AHRS mode). The accelerometers employed within the OrionPlus are equally highly regarded and are built into it at the company's advanced UK workshops where quality control is maintained to the highest standards possible. The OrionPLUS consequently offers a calculated MTBF (Mean Time Between Failure) of 30,000 hours while its key individual components are rated at 300,000 hours MTBF. A subsea version is also available rated to 3000 metres while the surface model can be used in the most extreme sea conditions to provide users with the valuable benefit of minimal downtime. The OrionPLUS has been designed to meet the demanding IEC 60945 and IEC 61162 standards. The new OrionPLUS INS is backed by TSS' global support network and the company's own engineers in Watford, Aberdeen and Houston.
