KVH Industries’ TACNAV Universal Multilingual Display (UMD) offers the latest in tactical display technology, capable of presenting navigation and other critical information in multiple languages for vehicle drivers and commanders as well as mortar crews and other warfighters.

In addition to breaking the language barrier, the TACNAV UMD offers an active dot-matrix design, delivering unparalleled flexibility. Each TACNAV UMD is capable of displaying easy-to-understand icons, messages, and pop-up menus, all of which can be configured to display the specific data that the user requires.

With its versatility and affordability, the TACNAV UMD is ideal for any military vehicle requiring a user-friendly interface for its tactical navigation system. Likewise, the rugged design and clear display make the TACNAV UMD an ideal interface for mortar and fire control systems as well as the perfect solution for presenting data available from digital Battle Management Systems.

The TACNAV UMD is controlled by the Arms Export Control Act (Title 22, USC Sec 2751 et seq.) and the International Traffic in Arms Regulations, ITAR, 22 CFR 120-130, and may not be exported from the United States or disclosed to a foreign person in the united States except as authorized by those regulations.
