Here is V1 of the Omega Flight Computer, also known as Omega-Nav, made for big rockets and spacecraft. It is a rigorous implementation of Aerospace Avionics Orchestration and Thrust-Vector Control (TVC) Forensics. Designed for high-power rocketry, it is made on a protoboard and will control the rocket on the way up and also hopefully on the way down too! The system enables finless flight by dynamic gimbaling of the rocket motor and explores sophisticated 6-DOF IMU Fusion, utilizing barometric-altimetry forensics for precise height telemetry and apogee-detection diagnostics. Every time there is an update I will be sure to publish it!

Technical Deep-Dive
- TVC Orchestration & Inertial-Fusion Forensics:
- The Orientation Logic-Hub: The system utilizes a Bosch BNO055 or MPU6050 for absolute Euler-angle diagnostics. Forensics involve the deterministic orientation of the rocket's longitudinal axis. The diagnostics focus on "Gimbal-Slew Rate"; ensuring that the TVC servos react to atmospheric perturbations with sub-millisecond latency to prevent diverging-oscillation forensics $(stalling)$.
- Thrust-Vectoring Heuristics: Forensics involve the mapping of PID error-terms $(Pitch/Yaw)$ to gimbal-angles $(\pm 5^\circ)$. The diagnostics ensure that the center-of-thrust remains aligned with the center-of-mass through dynamic thrust-vectoring harmonics.
- Barometric-Altimetry & Event-Trigger Analytics:
- The Atmospheric-Pressure Probe: Utilizing the BMP280 sensor, the system calculates altitude via the hypsometric equation: $h \propto \ln(P_0/P)$. Forensics involve "Apogee-Detection Logic," identifying the exact moment of zero vertical velocity $(V_z = 0)$ for parachute-deployment diagnostics.
- Black-Box Telemetry Diagnostics: Forensics involve the high-speed $(50\text{Hz})$ serialization of IMU and altimeter data to an SD-card. The diagnostics focus on "Write-Latency Mitigation," ensuring that telemetry-streams don't induce logic-skips in the primary flight-control harmonics.
Engineering & Implementation
- Avionics Signal-Integrity & Structural Forensics:
- Vibration-Damping Analytics: Rocket launches induce significant $G$-force and acoustic-vibration harmonics. Forensics include the mechanical isolation of the IMU to prevent "Vibration-Aliasing" in the accelerometer datastream.
- Current-Transient Diagnostics: TVC servos can pull significant bursts of current during rapid corrections. Forensics involve the use of large reservoir capacitors to prevent voltage-droop forensics on the Arduino's $5\text{V}$ logic-plane.
- Protoboard Hardening & Mechanical Diagnostics:
- The implementation utilizes a hand-soldered protoboard for maximum vibration-resistance, as seen in the videos. Forensics focus on "Solder-Joint Integrity" under high-$G$ loads, ensuring that avionics-power is maintained through the boost-phase.
Conclusion
Omega-Nav represents the pinnacle of Real-Time Aerospace Control Diagnostics.
