Through involvement with various projects at home and abroad,
Meisei continues to make history.
Since its incorporation in 1938, Meisei’s technology has been making history in many ﬁelds. Meisei’s technology has been consistently supporting the histories of meteorological observation and Space development in Japan.
We will continue to be involved in epoch-making projects through development of innovative products and systems.
Meisei developed its first radiosonde.
Meisei received the first order of 1,000 radiosondes. Three types of sondes were manufactured to measure cloud, wind, and temperature & humidity.
CMO-S49B code sending type radiosonde made in 1950
A weather robot was delivered to the Central Meteorological Observatory.
Meisei’s radio technology realized unmanned observation of precipitation, which would replace the conventional manned observation in meteorological stations, and made it possible to observe precipitation in mountainous areas as well.
Baby-T Rocket ⒸJAXA
Developed a rocketsonde.
Meisei developed a rocketsonde that observed the mesosphere thermosphere (altitude of 60 km above ground level). These rocketsondes were launched from the meteorological rocket observation center in Ayasato, Sanriku-cho (present Ofunato-shi), Iwate Prefecture. A total of 1,119 sondes had been launched by March 2001, when the rocket observations were ended.

by the Winter Party of the Japanese Antarctic Research Exploration
AMeDAS (Automated Meteorological
Data Acquisition System)
was delivered to JMA.
“AMeDAS” is a meteorological instrument that became popular among Japanese people with its simple and easy-to-understand name. This unmanned observation system was deployed at 1,300 locations throughout Japan to observe precipitation, wind direction, wind velocity, temperature, and solar radiation.
Very Long Baseline Interferometry (VLBI)
Meisei contributed to the development of “VLBI”, which observes radio sources of stars with a radio telescope for ultrawide measurement. It is now possible to detect tectonic plate motions in the order of 10cm/year with the VLBI technology, which is greatly contributing to the prediction of earthquake occurrence, etc.
[VLBI] installed in the Geographical Survey Institute
Seismic intensity meter was delivered to JMA.
Meisei developed the world first seismic intensity meter. Seismic intensity measurement achieved a great progress from the conventional somatosensory method. Seismic information captured by the Seismic Intensity Meter is transmitted through telecommunication lines, and promptly delivered to the population through TV and other media thus contributing to the rapid deployment of emergency and rescue teams in the initial stage of earthquakes.

(Airport Meteorological Observing System)
AMOSs are installed at 50 airports throughout Japan to observe weather conditions at the airports and transmit the data to the Civil Aviation Bureau and airlines. Serving an important role in the safe operation of aircraft.
Airport Meteorological Observing System (AMOS) at Haneda Airport
“Hayabusa” was launched aboard the M-V-5 Launch Vehicle.
“Early Warning Seismometer”
The Early Warning Seismometer, developed jointly by Railway Technical Research Institute and Japan Meteorological Agency, is equipped with an early earthquake parameter estimation. The “Earthquake Early Warning System”, which uses a seismometer to stop a train before it shakes, contributes to the safety of railway operations. Its advanced technology has been adopted by JR companies and the Japan Meteorological Agency.
CubeSat “WE WISH”
“WE WISH”, Meisei’s first ever CubeSat, was released into space from the international space station on October 4. It subsequently orbited the Earth successfully and was in operation for longer than had been originally planned – a total of 158 days.
“Hayabusa2” was equipped with Near Infrared Spectrometer (NIRS3), and The Deployable Camera (DCAM3).
“Hayabusa2″ was equipped with NIRS3 and DCAM3, NIRS3 find ubiquitous hydrated minerals on the surface by catch the reflected infrared, DCAM3 (Digital system) capture an image of Small Carry-on Impactor (SCI).”Hayabusa2” is going to return to Earth in 2020.
