• Lead efforts for the Modeling and simulation of landing performance analysis of HLS trajectories.
• Lead 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.
• Steward trade studies to assess navigation performance under dispersed model parameters to assess uncertainty of unknown model parameters, and evaluates navigation margins.
• Assess HLS commercial partner test data and partner sensors and models.
• Develop in-house models and/or integrate sensor models from HLS commercial providers into 6-DOF simulations such as the GeneraLized Aerospace Simulation in Simulink (GLASS) tool.
• Perform and steward 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++.
• Communicate navigation margin findings to HLS Chief Engineer and HLS commercial partners.
• Maintain and strengthen NASA HLS cross-center navigation team.
• Develop and coordinate 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.
• Provide technical leadership of a team of navigation engineers to achieve safe Moon landing and return to Earth.
• 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.
