Météomodem is a Research and Development (R&D) company created in 1992 bytwo engineers, Georges Ricaud and Patrick Charpentier. Météomodem began to design and manufacture equipements for maritime radio communications. Then, in connection with the main activities of its mother company Géolink, they specialized in designing, GPS positioning and Immarsat satellite communication. Marketing and distribution of these product were in charge of Géolink. Futher an enquiry of ESA (European Spacial Agency) in 1994, Météomodem has been involved into radiosounding. At this time, the question was find a high performance system to mesure accurately wind parametters in order to calculate and define wind gust dimension on Kourou launch site.
Founded in 1992, Meteomodem is a French company specialized in the field of the Upper-air observation, and more specifically in the domain of radiosounding. Today, it is one of the top leading radiosonde manufacturer and a major player in this specific business, Meteomodem customers include a large list of NMS’s (National Meteorological Services) worldwide including Meteo France among many others, but also international Research Institutes, Universities and Laboratories for Research or Air Traffic Management authorities (Like the ASECNA in Africa) or again Military and Army corps. Currently more than 120 Meteomodem systems (upper air stations) are operated in more than 60 countries throughout the world and are using Meteomodem radiosondes on a daily basis (Once or twice a day depending on their means). As a world reference in this niche market of radiosounding, Meteomodem never stop developing, diversifying its activities and skills to other of domains in meteorology and climatology.
Modem cultivates its difference by its particular business model, promoting innovation and cooperation with our customers and partners, while ensuring flexibility and proximity from the technical, operational and commercial aspect. All of our products are “Made in France”. Meteomodem is an exporting company; indeed, a significant part of our turnover is made worldwide. Modem is an active protagonist of the French know-how exportation worldwide. Moreover, it is a dynamic member of Prometeo, a French association gathering the top leading French manufacturers and that aiming at promoting our vision of Meteorology.
Meteomodem is deeply implicated in various radiosounding work groups, of course the WMO/CIMO Expert teams OPAG’s Upper at the WMO (World Meteorology Organization). It also participates of the European meteorology agency (EMS) or again the HMEI association, who regroups a large number of Meteorological Company around the world.
To that effect, we used a new specific balloon named ''Méduse'' (jellyfish) associated to a new Météomodem sonde GPS400PSK. The distinctive feature of the sonde consisted in using GPS positioning technology whereas only Loran C, Omega or radar tracking were available to measure wind parameters. This association Meduse-Modem sonde has been used successfully during VERHT1 and VERHT2 campaigns in 1996 and 1998. Following these encouraging result with the GPS400PSK, Météomodem engneers were motivate to develop a complete GPS radiosounding system with wind and PTU for meteorological needs.
