Open a case study for methods and plots, or go directly to public source where it exists.

ASTRA-OS command, flight-core, telemetry and assurance architecture.
02Verified software

ASTRA-OS

C++ flight-software baseline with command handling, mode logic, FDIR, deterministic fault campaigns and an interactive browser model.

Evidence boundary: Raspberry Pi execution demonstrates portability, not hard-real-time qualification.

  • C++17
  • CTest
  • FDIR
  • Monte Carlo
AeroFrame-DT finite-element response and failure-mode correlation plot.
03Educational analysis

AeroFrame-DT

Synthetic aircraft-fitting substantiation covering classical margins, finite-element response, tolerance effects and adverse statistical cases.

Evidence boundary: Educational, synthetic and non-OEM; this is not approved aircraft stress substantiation.

  • Stress analysis
  • FEA
  • Fatigue
  • Requirements
Fixed-wing seed-42 uncertainty campaign with 50 altitude histories.
04Representative SIL

Fixed-Wing Flight Controls SIL

Autopilot testing against actuator limits, gusts and model uncertainty, including a seeded 50-run campaign.

Evidence boundary: Uses a low-order representative model; it is not validated F-16 flight dynamics.

  • Python
  • PID
  • Monte Carlo
  • Regression tests
Technical orientation illustration for the rocket landing prototype.
05Exploratory prototype

Rocket Landing GNC

Early point-mass landing simulation used to define the next modeling and verification gates.

Evidence boundary: Current source supports one representative run, not a statistical landing campaign.

  • Guidance
  • Controls
  • Simulation
Concept visualization for TAMU-SPIRIT systems engineering and orbital payload operations.
06Internal program

TAMU-SPIRIT / ISS Payload

Requirements, engineering-change, thermal and review support for a student spacecraft payload program.

Evidence boundary: Program artifacts are limited and the role cannot be independently verified from public source.

  • Requirements
  • Trade studies
  • Change control
Interception robot technical illustration.
07Reported prototype

Interception Robot

Perception-to-actuation prototype organized around a measurable latency budget.

Evidence boundary: Source code and raw timing logs are not public, so exact performance is reported rather than independently verified.

  • Perception
  • Embedded control
  • Latency budgeting
Project KESTREL technical illustration.
08Archived design

Project KESTREL

Precision-landing UAV concept retained as an engineering design-review closeout.

Evidence boundary: The project ended at design review; no flight campaign was completed.

  • UAV design
  • Landing autonomy
  • Design review
09Pre-hardware

Project CHASER

Public relative-navigation reference implementation with geometry, a 12-state UKF, FDIR and replay scaffolding.

Evidence boundary: No hardware campaign or validated accuracy, timing or flight-readiness result exists yet.

  • Pose estimation
  • UKF
  • FDIR
  • Replay testing
