Important points about esa-star document formats:

  • The tender documents, duly signed when required, shall be submitted in pdf format containing no dynamic content. (i.e. no animations).
  • If required by ESA, specific tender components (i.e. PSS forms, planning charts, etc.) may have to be uploaded, also in their native format.
  • Only unencrypted files, which are not password protected can be uploaded. (ESA ensures that files are encrypted after upload to esa-star). Maximum file size is 250 Mb per file.
