TSS Launches New Inertial Navigation System
The new Orion INS (Inertial Navigation System) from TSS (International) Ltd. was shown for the first time last month in Southampton. Orion supersedes the company's Marinus AHRS and incorporates many years of technical expertise in motion sensor technology. Orion is aimed at meeting the needs of users in the offshore subsea construction and survey industries, as it is designed to provide precise attitude, heading and heave data and is suitable for a wide range of applications such as supporting multibeam sonar surveys or the construction of major seabed installations. The subsea version is available rated to 6,000 m while the surface model can be used in the most extreme sea conditions to provide users with the benefit of minimal downtime. Orion is the first INS to be designed entirely by TSS and will be try and consequently offer users the reassurance that comes from working with proven advanced technology. The accelerometers employed within the Orion are equally highly regarded and are built into the new Orion at TSS International's U.K. facility. The Orion system consequently offers a MTBF (Mean Time Between Failure) of 30,000 hours while its key individual components are rated at 300,000 hours MTBF. The performance of the Orion's components and software means that users will benefit from heading accurate to 0.1º sec lat and roll and pitch measurements to within 0.025º through a range of ± 90°. Heave measurements are accurate to 5 cm or 5 per cent over ranges to ± 99 m and free inertial positioning remains accurate to 5 NM/hour.

assembled at the company's headquarters in Watford, U.K. TSS engineers have dedicated two years to the creation of a software algorithm that will exceed industry expectations for performance and reliability. The algorithm will process the data generated by three separate ring laser gyros (RLG) that have been chosen for their dependability and accuracy. They can be used at operating temperatures ranging from -10°C to +55°C and require a settling time of less than 15 minutes. Manufactured in the US, the RLGs are widely used in the aviation indus-
LinkQuest Debuts "World's Smallest" DVL
LinkQuest Inc. recently rolled out the NavQuest 600 Micro DVL, a development that the company touts as "the world's smallest Doppler Velocity Log." In its standard config-
uration with pressure housing, NavQuest 600 Micro DVL is about 12.6 cm in diameter, 17 cm in length and weights less than 1.2 kg in water. In the OEM configuration without pressure housing, the NavQuest 600 Micro DVL weighs less than 0.8 kg. The NavQuest 600 Micro DVL is designed to reach up to 110 m in maximum altitude (range) with an accuracy of 0.2% +/- 1 mm/s. LinkQuest's acoustic Doppler technology also achieves the smallest minimum altitude of up to 0.3 m which allows robust navigation very close to
the seabed. The standard depth rating of the Micro DVL is 800 m with options for 1,500, 3,000 and 6,000 m.
