Supporting Aeronautical Communications With
Next Generation Satellite Systems
Posters


Researchers: Yadong Shang, John Baras, Michael Hadjitheodosiou

Synopsis: The US airspace is reaching its capacity with the current Air Traffic Control System. The FAA has undertaken several initiatives to modernize the National Airspace System (NAS) to ensure the safety of the increasing number of flights. Next generation satellite systems offering global coverage and high capacity can be an alternative to the terrestrial communication systems and the challenges that need to be addressed in doing that will be the focus of this study.

Tools: This project is using OPNET by OPNET Technologies, Inc.- Satellite_Tool_Kit by Analytical Graphic, Inc.

Optimizing Communications for Constellation Space Missions  


Researchers: Yingyong Chen, John Baras, Michael Hadjitheodosiou

Synopsis: This project is to address the communication requirements for constellation space missions, develop the framework for studying the operational communication trade-offs for typical constellation missions. We developed a simple prototype dynamic routing algorithm for this type of mission. As an example, we studied Magnetospheric Multiscale Mission (MMS) in detail, developed fairly detailed OPNET models for this mission and performed simulation and obtained some preliminary simulation results.

Tools: This project is using OPNET by OPNET Technologies, Inc.- Satellite_Tool_Kit by Analytical Graphic, Inc.

Traffic Modeling, Analysis and Scheduling for
Dynamic NASA Communication Networks		  


Researchers: Hui Zeng, John Baras, Michael Hadjitheodosiou

Synopsis: Study ways to optimizate key parameters--bandwidth, efficiency and delay, for a dynamic operations next generation NASA communication network. Our model considers a specific case, which inludes the TDRS relay system and some sample spacecrafts. We will model the traffic sources in those spacecrafts and use suitable scheduling mechanisms in the source packaging and data relay channel (TDRSS), to try to improve performance in this dynamic environment.
