Global Digital Solutions Inc. announced it has contracted JDA Aviation Technology Solutions (JDA), an internationally known technical services and consulting firm specializing in safety, certification and the development of solutions bridging the needs of airlines, aircraft manufacturers, airport authorities, government organizations and aviation industry providers. Under the agreement, JDA will provide an independent analysis and assessment of the patent pending (PP) Vertical Stacking Air Traffic (VSAT) Management System and its potential application in the National Airspace System (NAS) for Global Digital Solutions, Inc., (GDSI). GDSI has entered into this agreement with JDA to assess the potential application of VSAT, a new concept in air traffic management, specific to arrivals at airports. VSAT coupled with Precision Approach Landing System (PALS) technology, will enable aircraft to independently manage their descent and arrival at an airport, thus saving fuel and time with a significant reduction in noise due to the descent profile. VSAT takes advantage of the Automatic Dependent Surveillance–Broadcast (ADS–B) surveillance technology coupled with the PALS situational awareness IR visual system for safety verification. In addition, wake turbulence avoidance enabled by VSAT will contribute to aviation safety.
