KVH Industries Inc., of Middletown, said yesterday that it received a sole-source contract from the U.S. Army Tank and Automotive Command for the purchase of KVH’s vehicle navigation systems for use on Army combat vehicles. The contract is potentially worth $11.5 million over five years. “This new sole-source contract is a reaffirmation of the value TACNAV offers U.S. and allied war-fighters through its ability to consistently support applications in a wide range of demanding military environments, including vehicle navigation, integration with digital battlefield management systems, and precision stabilization and pointing,” said Dan Conway, vice president of business development for KVH. “We look forward to continuing our long-standing relationship with TACOM as well as the ongoing opportunity to ensure that U.S. servicemen and women have the critical navigation and guidance capabilities necessary to enable them to carry out their missions quickly and effectively, and then come home safely.” KVH’s military vehicle navigation systems provide unjammable, precision navigation, heading and pointing data for vehicle drivers, crews and commanders. The system also serves as a link between each vehicle and the overall digital battlefield, making each unit a node in a secure military network that consolidates a wide range of tactical data to provide detailed information to individual units and military commanders.
