About CAUG

CAUG Frequentis Comsoft and Frequentis California AMHS users

Frequentis Comsoft founded CAUG - the Collaborative Aeronautical User Group - in order to exchange information with all stakeholders involved in the future evolution of AMHS and SWIM. The goals of the Collaborative Aeronautical User Group are to share experiences, requirements and visions, to benefit from a joint strategy and forward planning and to evolve Comsoft’s & Frequentis’ AMHS portfolio.

CAUG provides a platform for open discussion within the group in order to

  • Facilitate the smooth introduction and global availability of AMHS,
  • Get a comprehensive view of the requirements and visions of the AMHS world,
  • Enhance the functionality, usability and quality of our message handling products,
  • Benefit from a joint strategy and planning, and
  • Get an insight on the Frequentis Group's message handling solutions and working procedures.

Annual Meetings

Since the CAUG was founded in 2007, 54 organisations from 49 countries have joined the community. The annual meeting organised by the Frequentis Group steadily gains importance. As opposed to regional conferences, CAUG meetings bring together members from all ICAO regions to exchange their experience.
