Job Summary

The Boeing Company, Integrated Defense Systems                                            JUL 01 – NOV 10

Principal Software and Simulation Engineer

Has subject matter expertise in software development, testing, & validation, modeling and simulation, spacecraft subsystem design & analysis, and systems engineering.

Computing, Data Processing, Telemetry and Embedded Systems:

*        As an operational analyst for military satellites monitored, analyzed, and maintained the Data Processing Subsystem/Onboard Computing System performance, including flight software, ground software, and TT&C, for an operational space system. 

*        Developed a software tool using Matlab GUI script to better visualize telemetry data from arbitrary file formats.

*        Developed a software tool using Python that takes a preformatted vehicle telemetry data file and parses it by date, time, data value, and/or telemetry command value.

*        Developed a software tool to automatically extract specific telemetry commands from a single or a set of files that included a large number of telemetry commands. 

*        Created a real time embedded system using an 8051 microprocessor to determine pressure, temperature, and attitude data.  Performed all design, assembly, and testing of hardware with software coded using micro-C and assembly language.

Astrodynamics and Trajectory Software:

*        Developed unique software tools for spacecraft trajectory analysis including launch, orbital states, and reentry.  Conducted reentry trajectory analysis for the Columbia accident investigation. 

*        Developed an orbital integrator software to determine the impact of perturbations on orbital trajectories (Python coded).

*        Developed unique spacecraft drag modeling software tools using 3-Dimensional models (in Python) and rarefied gas simulations using Direct Simulated Monte Carlo (DSMC) methods. 

*        Developed a unique Reentry Trajectory Tool, which accounts for the spinning of objects during reentry (Python coded). 

*        Developed software used for automated spacecraft stationkeeping using Python and PC Trace. 

GNC & Attitude Control Software:

*        Developed a 3-dimensional tool for visualizing spacecraft and estimating the effective aerodynamic force and torque on complex vehicles (Python coded).

*        Developed methods and tool for mapping the effective aerodynamic force and torque on space objects by orientation attitude in 3-dimensions (Python coded).

*        Developed an Attitude Integrator program called ATTINT to examine the dynamics of vehicles given an arbitrary force and torque input (Python coded). 

*        Invented a method for determining the space vehicle center of gravity by conducting a series of small thruster maneuvers and using sensor inputs from reaction wheels.

*        Boeing Invention Award for patent submission entitled: “Finding Indeterminate Angle of Satellite Solar Arrays using Sun Sensors and Magnetometers”, 2004.
