Autonomous Intelligent Network and Systems

Overview
The Autonomous Intelligent Network and Systems (AINS) is

"[a] DARPA initiative (circa 2002) for developing a system intended to operate independently from the Global Positioning System (GPS) with a "pseudo-GPS" system in the event the former is jammed by an adversary. AINS would link various unmanned and manned systems without the need for human intervention, except to assign specific tasks."
