- Design, develop, implement, verify, and test algorithms, software, and simulation tools to perform guidance, navigation and control (GNC) of autonomous unmanned aircraft.
- Develop control laws to meet air vehicle performance, flying qualities, and stability margin requirements both on ground and in flight.
- Design outer and inner loop control laws and associated logic and autonomy functions.
- Develop air vehicle system linear and non-linear dynamic simulation models and integrate models into software and hardware-in-the-loop simulation environments.
- Perform performance and flying qualities analysis.
- Support non-linear simulation and hardware-in-the-loop lab testing.
- Support flight test activities and analyze air vehicle flight test data.
- Develop analysis to support design reviews at different stages in a development program, such as PDR, CDR, etc.
This position may be filled at either the Principal GNC Engineer level or the Senior Principal GNC Engineer level, depending upon the qualifications below.
