ORION is Optimal Ranging Inc. new flagship product for Underwater Utility Surveying. Extending LIBRA's Fieldsens technology, ORION now includes MultiSens and is available in two, four or six sensor configurations. ORION is rated to a depth of 2000 m and is therefore ideal for use in deep-sea surveys with ROV's. It may also be mounted on other platforms such as a sled or a wing. ORION is integrated with leading hydrographic survey software including EIVA, QINSY and HYPACK.

The ORION system can be ROV mounted or deployed in a towed of fixed-hull set up. For deeper cable and pipeline mapping projects in larger bays or on the continental shelf, the system can be towed over or positioned above the seabed by depressor or mounted on a carbon fiber sled, respectively.
