To receive, check and forward automatically, meteorological data and products according to the WMO standards.


All National Meteorological Serices including Regional Telecommunication Hubs (RTH)


Beating heart of your systems
The Automatic Message Switching System (AMSS) is the central element in a high technology meteorological environment, and the heart of meteorological telecommunication.

  • Interconnection of meteorological devices, share data product internaly and with the meteorological world.
  • Developped by Météo-France (Toulouse-RTH) to be easily configurable and upgradable
  • Designed to take into consideration future WMO standards and particularly WIS.


TRANSMET is fully compliant with all applicable protocols, procedures, regulations, and standards including WMO386.
TRANSMET is a reliable, upgradable solution operated daily since more than 10 years by several Regional Telecommunication Hubs (RTH) and major National Meteorological Services
TRANSMET manages 160 channels and switches more than 8 gigas of data a day, without any interuption since 1998 at Météo-France in Toulouse
