The short version

  • Only AGI STK has a free tier, so it costs nothing to try first.
  • Each has a real cost: AviaSIM Pro limited to civilian flight simulation experience, not professional pilot certification training; AGI STK sTK is sold as a ladder of separate licences, STK Pro, STK Premium Air, STK Premium Space and STK Enterprise, so mission areas are gated behind different products
  • They diverge on capability: AviaSIM Pro covers High-fidelity flight models, AGI STK covers Orbit analysis.
