Where each one falls short

Documented limitations, not opinions. Every one is a constraint you would hit in normal use.

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
  • Further capability is sold as separate add-on toolkits including TETK, the RF Channel Modeler and the STK Missile Toolkit
  • Distributing an application built on STK Engine to end users requires each of them to hold an Ansys STK Engine Runtime License
  • Free access is limited to students at accredited institutions and to time-limited trials
  • No price, minimum or cost driver is published for any STK tier
