Why STK Parity Matters

STK sets the commercial benchmark for orbital analysis, so reaching parity provides three clear advantages for Darksun teams:

1. Credibility with mission stakeholders – Matching STK’s physics coverage (SRP, higher-order harmonics, advanced atmosphere) lets analysts and operators trust Darksun for high-consequence work.
2. Unified workflow – Achieving parity eliminates the “simulate in STK, visualise in Darksun” split and keeps planning, rehearsal, and handoff in one browser-native stack.
3. Faster iteration – When the browser simulator delivers the same answers as the heritage desktop tool, engineers can iterate on mission profiles without exports, conversions, or license juggling.

This initiative focuses on the physics gaps that have the biggest operational impact—solar radiation pressure, gravity harmonics beyond J2, and precision validation against well characterised reference trajectories.
