Transformational Satellite Communications System (TSAT) lessons learned: Perspectives from TSAT program leaders

The Transformational Satellite Communications System (TSAT) Program was intended to extend the Global Information Grid (GIG) to disadvantaged users through a robustly interconnected, high capacity space-based capability. Prior to its cancellation primarily for affordability, the $3B TSAT investment demonstrated many organizational, enterprise and technological innovations to deploy the next generation transformational communication technologies. While the government investment strategy has changed, many of these innovations remain relevant and useful to any system-of-systems acquisitions. With inputs from across TSAT´s senior government acquisition and Federally Funded Research Development and Center (FFRDC) leadership, this paper explores the TSAT´s lessons learned in support of future enterprise program planning. The paper also explores the technical challenges associated with interconnection of tactical Internet Packet (IP)-based communications systems. The paper´s findings include governance successes and challenges across several management areas.
