GPU-Accelerated Orbit Propagation with High-Fidelity Solar Radiation Pressure Modeling

GPU orbit propagation just got a practical speedup: a Vulkan implementation of high-fidelity solar radiation pressure modeling reaches up to 15.2x faster full-trajectory runs. The work keeps numerical differences below 5e-4 versus the prior OpenGL path, while also showing that articulated solar panels can materially change long-term results. For teams doing simulation-heavy space games or tools, it’s a useful reminder that accuracy and throughput can coexist.
