2004 ACAST Workshop

The 2004 NASA ACAST Workshop took place in Cleveland, Ohio, August 24-25, 2004 at the Marriott Key Center.

The 2004 ACAST Workshop presented an overview of the ACAST Project (in the Space Based Technologies Project of the Airspace Systems Program), along with the project’s objectives and that of the several subprojects that had been defined to support it. NASA also sought comments from relevant members of the aviation community regarding the plan, approach to development of short-, mid-, and long-term technologies, and suitable outputs.

With the formulation of the Advanced CNS Architectures and Systems Technology (ACAST) Project, NASA responded to recommendations from the US Aerospace Commission, the US aviation community, and the many studies and analyses that have demonstrated the need for an advanced CNS infrastructure to address system deficiencies and to support the transition to the future National Air Space (NAS).
