Precision Autonomous Virtual Flight Control

Award Year / Program / Phase: 2012 / SBIR / Phase II
Agency / Branch: DOD / ARMY
Principal Investigator: Chengjian He, Vice President of Researc – (408) 523-5100
Award Amount: $779,975.00
Abstract:
Flight simulation provides a cost effective tool for testing aircraft systems. Testing avionics systems across a particular flight profile requires driving the simulation through the flight profile to generate the required simulated sensor data. Testing avionics systems with a human pilot is costly… More

Next Generation Aircraft Simulation Technology

Award Year / Program / Phase: 2013 / SBIR / Phase I
Agency: DOD
Principal Investigator: Hossein Saberi, Vice President of Engineering – (408) 523-5100
Award Amount: $149,998.00
Abstract:
ABSTRACT: There is a need to utilize mobile computation devices to extend flight training from centralized facilities to remote field stations. Current limitations in the computational capabilities of mobile computing devices require that the software be partitioned between a more powerful… More
