Space-Related Applications of Forth

Compiled by James Rash, NASA Goddard Space Flight Center Greenbelt, Maryland

Introduction.

The following table presents space-related applications of Forth microprocessors and the Forth programming language, including

  • spacecraft flight system controllers
  • on-board payload experiment controllers
  • ground support systems (e.g., communications controllers and data processing systems)
  • hardware or software used to build or test either flight or ground systems.

Developers are requested to supply table updates and corrections, as well as information regarding relevant projects not already included, as appropriate. Please send information, comments, and suggestions to the author of this web page. Authorization for release of the information is the responsibility of the contributor.

A "+" marked in the left column indicate that the item is new or updated since the last version.

Please notify the author concerning any non functional URLs, links, or contact information in the table.
