Questiny Group

On April 10th, Questiny completed the final report for the Phase I SBIR Option. The final report titled, Land-mobile Satellite Communications-Improved Mathematical Methods for Stressed Environments: Phase I Option Final Technical Report, outlined the software design for a new satellite network performance simulator. This performance simulator has been designed to simulate the performance of mobile terminals operating over satellites. While mobile terminals have been used over satellites before, the size of the networks along wtih the diversity of channel environments creates scenarios that exceed the current capabilities of satellite performance simulators. We have designed a new simulator that can model both commercial and military mobile communications networks and environments. The SBIR program will develop the underlying technology for this simulator. One of the first applications for this simulator will be the Navy’s MUOS Program for mission planning. SPAWAR has expressed interest in customizin the application for this program.
