The HLS Navigation Aerospace Engineer models the navigation systems of the Human Lander System (HLS) for NASA's HLS program. From sensor fusion and sensor model development to descent dynamics and visualization, this position will require a well-rounded background of navigation skills, experience with computer programming, and the desire to perform high fidelity analyses to ensure successful navigation and landing of the HLS systems.

Description

The Amentum Space Exploration Division (ASED) Guidance, Navigation, and Control (GN&C) team is a high performing group executing challenging tasks to design and integrate GN&C systems for NASA projects ranging from NASA's Space Launch System(SLS) to NASA's Human Lander System. We are searching for highly qualified candidates to support NASA's Flight Dynamics Team in the Guidance, Navigation, & Mission Analysis branch at NASA's Marshall Space Flight Center. This exciting work will serve as a critical step in sending humans back to the Moon, Mars and beyond!

ASED offers a partnership in which you can grow personally and professionally within a framework of strong leadership, competitive compensation, and rewarding career paths. Come join our team!

Job Functions:

• Participate in the insight/oversight effort of the MSFC HLS GNC group with regards to all aspects of the navigation system

• Assist with Modeling and Simulation efforts to analyze the landing performance of HLS descent trajectories to the surface of the Moon

• Lead efforts to integrate all relevant models into a MATLAB/Simulink 6-DoF simulation, including Terrain Relative Navigation (TRN), Inertial Measurement Units (IMUs), Radar, Lidar, and Camera sensor models

• Tune, modify, and enhance Kalman Filter sensor fusion capabilities and assess limitations of various partner approaches

• Perform trade studies to assess navigation performance under dispersed model parameters to assess uncertainty, and evaluate navigation margins for government Design Reference Missions and government partners

• Assess partner test data and partner sensors and models

• Communicate directly with partners about the risks of their design and provide constructive feedback on possible improvements

• Tasking may also include use or development of visualization tools of landing sites to aid navigation analysis.

• Execute/modify existing software/scripts in Python, Matlab, Fortran, C+Provide demonstrated (minimum of 4 years) expertise to support the Human Landing Systems (HLS) program navigation team as part of the Guidance Navigation and Control (GNC) discipline. Specifically, this task will entail deep technical analysis as part of a team of navigation engineers helping model HLS descent trajectories to the surface of the Moon. Programming skills and mentoring abilities are highly desired.
