OVERVIEW

Orion INS has been specifically designed for the demanding hydrographic survey, offshore construction and ROV operations markets. Orion incorporates three single axis ring laser elements and three highly accurate accelerometers. These specific components, widely used in many of the world's commercial aircraft, were chosen for Orion because of availability, accuracy and their very high mean time between failures. These core elements enabled the TSS research and development team to design this high specification Inertial Navigation System which is configured and controlled by the latest easy-to-use interface - OrionView.

Available in surface and subsea versions, Orion provides 0.1° secant latitude RMS heading and a position accuracy of 5nm/h free inertial drift as well as other important performance parameters.
