Intervehicular Information System (IVIS): The Basis for a Tactical Information System

The Intervehicular Information System (IVIS) is a computer driven communications network embedded in the vehicle electronics of the M1A2 main battle tank now entering international service. The system uses multifunction controls and displays to provide a graphics user interface for human-machine interaction, embedded sensors for the information integration, a distributed multiprocessor computer system for information processing, and a digital communications channel. While the Intervehicular Information System offers many features and benefits to the operators that are using it, its primary interest to commanders is its capability to integrate combined arms operations in a rapidly moving situation and support essential graphic and digital information requirements for mission accomplishments to provide the basis for automating mobile combined arms force integration. IVIS supports this by networking mobile information systems which provide a battle command capability. A discussion of IVIS and other emerging information system capabilities provides insights into the challenges of integrating information systems with mobility technologies as is required in the Intelligent Vehicle Highway System.
