About the job
Navigation System Architecture & Design
- Establish navigation performance requirements and error budgets for safety-critical applications
- Support decomposition of navigation requirements into allocations for sensors, estimation algorithms, and software components
- Design detailed software architecture for state estimation implementations, including module interfaces and data flow
Algorithm Development & Implementation
- Design and implement Extended Kalman Filter algorithms for navigation applications, with broad understanding of state estimation theory and alternative filtering approaches
- Implement tightly-coupled and loosely-coupled GNSS/INS integration algorithms
- Integrate diverse sensing modalities (vision, RF, celestial etc.) into multi-sensor fusion framework for GPS-degraded environments
- Develop fault detection, isolation, and recovery (FDIR) strategies for navigation systems
- Implement integrity monitoring and protection level calculations for safety-critical operations
Certification & Verification
- Develop verification and validation test plans for navigation algorithms
- Conduct performance analysis including Monte Carlo simulation, covariance analysis, and flight test data evaluation
- Document navigation system design, requirements allocation, and compliance evidence
- Support safety assessment activities including failure modes and effects analysis
Technical Leadership
- Provide technical guidance on navigation architecture and state estimation approaches
- Support trade studies evaluating navigation sensor suites and fusion strategies
- Mentor junior engineers on state estimation theory and implementation
