Canadian Hydrographic service choose Orion from Teledyne

The Canadian Hydrographic Service (Quebec region) has become the newest user of the Orion Inertial Navigation System from Teledyne TSS. The Orion INS is the most advanced inertial navigation system ever produced by the company and it will be used aboard the Canadian Coast Guard vessel F G Smith. The Coast Guard undertakes projects for the Canadian Hydrographic Service and will use the Orion for survey operations on its behalf in the St Lawrence Seaway.

The Orion was chosen after an extensive evaluation programme in which it was compared with all of its leading competitors. It has been supplied through ROMOR Atlantic Ltd which is the Teledyne TSS representative in Canada and it is presented as the optimum solution for all demanding hydrographic survey, offshore construction and ROV operations.

The Orion is aimed at users needing 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 multibeam sonar surveys or the construction of major seabed installations. The subsea version is available rated to 6000 metres while the surface model can be used in the most extreme sea conditions to provide users with the valuable benefit of minimal downtime. Dependability has been built-in by with the painstaking selection of components and software developed to meet the demands and expectations of its users.

The INS employs an advanced and highly dependable algorithm that processes the data generated by three separate ring laser gyros (RLG) 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 USA, the RLGs are widely used in the aviation industry 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 the advanced Teledyne TSS workshops in the UK where quality control is maintained to the highest standards possible. The new 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.
