About the NanoDynamics Orbital Engine
NanoDynamics combines analytical Keplerian mechanics, high-order numerical perturbation integrators, Symplectic Hamiltonian Physics-Informed Neural Networks (PINNs), and physical ESP32-S3 microcontroller Hardware-in-the-Loop (HIL) validation.
1. J2–J4 Zonal Harmonics & Drag
Full Earth oblateness perturbations (J2, J3, J4), exponential & NRLMSISE-00 atmospheric drag, solar radiation pressure (SRP), and third-body Moon/Sun gravitational attraction integrated via adaptive RK45 and Velocity Verlet schemes.
2. Symplectic Hamiltonian PINNs
Standard neural networks suffer from secular energy drift over multi-orbit rollouts. Our Symplectic Hamiltonian Projection guarantees conservation of specific mechanical energy within <10⁻⁶ relative drift while accelerating inference by 40×.
3. ESP32-S3 Hardware-in-the-Loop & Breakup Cascades
Real-time orbital state vectors stream over ESP-NOW / USB-Serial to physical ESP32-S3 nodes running quantized C++ PINN inference, paired with NASA Standard Breakup Model Keplerian debris cloud propagation.
