Kalman Filtering Inertial Navigation Jobs in Alabama

We have an exciting opportunity for a Navigation Lead Engineer for Human Landing Systems to join our ESSCA contract team at NASA Marshall Space Flight Center in Huntsville, AL. 

Job Functions:

• Lead the insight/oversight effort of the HLS GNC group (across NASA centers) with regards to all aspects of the navigation system
• Leading efforts for the Modeling and simulation of landing performance analysis of HLS trajectories
• Leading efforts for the integration of all relevant models into the simulation, including on-orbit estate estimation using ground tracking (e.g. range and doppler form Deep Space Network stations), on-board state estimation fusing inertial measurements with terrain relative sensing such as optical, radar, lidar measurements
• Stewards trade studies to assess navigation performance under dispersed model parameters to assess uncertainty of unknown model parameters, and evaluates navigation margins
• Assesses HLS commercial partner test data and partner sensors and models
• Develops in-house models and/or integrates sensor models from HLS commercial providers into 6-DOF simulations such as the GeneraLized Aerospace Simulation in Simulink (GLASS) tool
• Performs and stewards deep space navigation studies to assess HLS partner's navigation performance using FreeFlyer, MONTE or JSC-Linear Covariance Tool (SIGMA)
• Execute/modify existing software/scripts in Python, Matlab, Fortran, C++
• Communicates naviation margin findings to HLS Chief Engineer and HLS commercial partners
• Maintains and strengthens NASA HLS cross-center navigation team
• Develops and coordinates with the GNC discipline strategic planning for growing navigation expertise at MSFC

Provide demonstrated (minimum of 10 years) expertise to support the Human Landing Systems (HLS) program navigation team at the level of a Subject Matter Expert, as part of the Guidance Navigation and Control (GNC) discipline. Specifically, this task will entail technical leadership of a team of navigation engineers achieve safe Moon landing and return to Earth. Programming skills and mentoring abilities are highly desired.

Qualifications

A degree in Aerospace Engineering, Mechanical Engineering, Physics or related field from an ABET accredited institution is required. Typical experience requirements are:

• Ph.D., with minimum of 14 years of experience,
• MS with at least 18 years of experience, or
• BS with at least 20-25 years of experience.

To be successful in this position, the applicant must be detail oriented, work independently and collaboratively, possess strong communication and interpersonal skills, and will typically possess some of the following skills:

• Orbit Determination and Deep Space Navigation (Free Flyer, ODTK, MONTE, GMAT, Linear Covariance)
• Radar, LIDAR experience
• IMU, accelerometer, rate gyro modeling, GPS
• Terrain Relative Navigation
• Kalman Filtering and sensor fusion.
• Dynamically model descent systems
• Python, Fortran, C++ , Matlab & Simulink programming experience
• Support the design, integration, and analysis of GN&C products.
• Configure, conduct, and analyze 6-DOF Monte Carlo simulations.
• Familiarity with Linux, Bash, and the use of computational clusters/servers
• Proof of U.S. Citizenship is required.

The candidate is REQUIRED to have the following skills and experiences:

• Significant navigation experience
• Technical leadership experience
• Deep space navigation including ground tracking orbit determination or similar experience
• Onboard strap on navigation, including IMU, Radar/Lidar, sensor fusion, and Kalman filtering or similar experience

Duties

Day to day activities include:

• Technical leadership of the HLS navigation team's modeling and simulation of HLS system, including simulation integration, visualization, analysis, and trade studies
• Interfacing with commercial HLS partners and other NASA centers
• Debriefs to HLS partners and HLS Chief Engineers
• Perform and/or steward Deep Space Navigation studies, including Orbit determination accuracy of the HLS though its trajectory using FreeFlyer, MONTE and/or LinearCovariance (SIGMA) tools
• Dynamic modeling of the HLS trajectory
• Creating, editing and debugging software written in Python, Matlab, Fortran, and C/C++.
• Optimization and improvement of analysis tools and GN&C models.
• Working with GN&C leads and other engineering disciplines.
• Supporting the verification and validation of technical products.
• Preparing and presenting technical reports and briefings.
