KVH Fiber Optic Gyros Help Guide Remotely Operated Vehicles Through the Deep Seas


Deep-sea ROVs Use KVH FOGs and Digital Compass Technology to Find Their Way on Voyages of Exploration

MIDDLETOWN, RI – August 25, 2005 – Fascinating creatures and tremendous treasures are found in the deepest, darkest depths of the sea. For the human race to seek them out, we depend upon remotely operated vehicles (ROVs) that find their way through deep waters and crushing depths thousands of meters below the surface. ROVs are used in a variety of applications, including oil exploration, undersea construction, and research and salvage operations that have located long-lost shipwrecks such as the Titanic and the Bismarck and exotic deep-sea creatures that lurk along the ocean floor. To successfully control the ROVs and explore these depths, ROV manufacturers are turning to the precision fiber optic gyros (FOGs) and compass sensors developed by KVH Industries, Inc. (Nasdaq: KVHI).

Subsea 7 (, a company that owns and operates more than 100 ROVs worldwide, depends upon KVH FOGs on their Tuna 2 and Centurion 25 ROVs. “We are really impressed with their reliability, as they’ve done over 5,000 hours of use without a single failure in the last three years,” explained Clovis Galdino, Subsea 7’s operations manager. “They are also light, relatively small and of low power consumption, which has made installation a lot easier. We are pleased to recommend these gyros as a sound and cost effective solution for ROVs.”

With their all-fiber design and patented Digital Signal Processing (DSP) technology, KVH’s FOGs offer high reliability, superior accuracy and performance, and exceptional vibration, shock, and acceleration survivability at an affordable cost. KVH precision FOG products are used in diverse commercial and defense-related applications requiring a high level of accuracy. Supplementing KVH’s FOG family is its proven C100™ digital compass engine, a stand-alone sensor subsystem based on KVH’s fluxgate compass technology. The C100 outputs extremely accurate heading data in six user selectable digital or analog formats and can easily direct any underwater mission, whether it is for scientific research or undersea filming.

Silvercrest Submarines (, a company that specializes in manned submarines, ROVs, and submarine operations, employs the KVH C100 digital compass engine, according to Silvercrest’s Alan Whitefield. “We use a KVH fluxgate compass on one of our six-man submarines. It works extremely well and is ideal for our application.”

KVH’s guidance and sensor systems are used in an array of autonomous vehicle and precision guidance applications. Carnegie Mellon University’s “Red Team” selected the KVH DSP-3000 FOG for use in two autonomous vehicles designed to race 175 miles across the Mojave Desert terrain in ten hours or less, without a driver, as a part of the Defense Advanced Research Projects Agency’s (DARPA) 2005 Grand Challenge. And in another undersea application, KVH’s TG-6000 inertial measurement unit (IMU) is undergoing final testing as a key component in the guidance package designed for the U.S. Navy’s next-generation MK54 lightweight torpedoes.
