Controller design, simulation, analysis, and troubleshooting
- Led the effort to identify and correct an intermittent instability in the
STSS track gimbal controller due to the interaction of an incorrect anti-windup implementation
with inertial sensor noise near the gimbal singularity.
- Successfully managed a small contract to re-tune the STSS controller to increase
robustness to uncertainty in the underlying physical system.
- Derived susceptibility of the VIIRS line-of-sight to spacecraft disturbances.
Included updates to the Simulink model, integration with an updated structural model
generation of methods to assess requirements based on
the model, and generation of a model description document for
use throughout the life of the VIIRS program.
Calibration and estimation design
- Designed, implemented and tested the distortion calibration tool for the
STSS acquisition sensor to correct repeatable line-of-sight errors in the
STSS acquisition sensor based on observations
of a laser ground source from a known location.
Challenges included:
basis function selection and quality assessment;
quality assessment of curve fit;
handling of outlier/noise data points;
atmospheric distortion and uncertainty;
time/budget constraints.
System engineering and system analysis
- Owned requirements family on a space program. Responsible for system error modeling;
auditing of input analyses and data;
identifying and filling missing pieces (white space);
selling requirements to customer.
Test design and test data analysis
- Designed, executed, and analyzed tests of the geometric algorithms on the
STSS sensor during thermal vacuum testing. Corrected SW errors
in algorithms calculating earth spin rate and line-of-sight projection
to the ground.
- Led a small team to process
100's of gigabytes of data from more than 200 EMI sweeps
during a five month EMI test. This included tool development,
database design and implementation, data logging, report generation,
shift scheduling, and skills training.
Section manager
-
Responsible for performance feedback, career development, staffing,
mentoring and training, and direct technical support for a team of
11 engineers. This team has supported algorithm development and
implementation for electro-optical systems (tactical and space).
Currently my team is focused on data analysis and
requirements sell-off for the VIIRS sensor.
