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.
1939
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.
1948
Radiosondes were delivered to the Central Meteorological Observatory.
Meisei developed “CMO-S48B code sending type radiosonde,” adopting the then innovative digital method. This product was delivered to the Central Meteorological Observatory and contributed to the establishment of reputation as “Meisei renowned with sonde”.
CMO-S49B code sending type radiosonde made in 1950
1952
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.
1955
Japan’s first electric instrument
launched by a rocket.
Meisei developed and delivered an FM-FM telemeter transmission system for the “Baby-T rocket” in 1955. The successful launch made us the Japan’s 1st manufacturer of electric instruments to be installed in rockets.

1964
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.
1969
Meisei’s instruments were employed
by the Winter Party
of the 11th Japanese Antarctic
Research Exploration.
Meisei’s instruments played an important role in the observation of Aurora Polaris by rocket or balloon in the Antarctica from 1969 until 1985 ( for 16 consecutive years ), when the rocket experiments officially completed, and Meisei involved in all Aurora Polaris’ observations.

1974
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.

1982
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.

1983
NASA’s Space Shuttle launched with Meisei’s products.
Meisei delivered six mounted devices for Japan’s first artificial aurora experiment (SEPAC) using a space shuttle.
*SEPAC (Space Experiments with Particle Accelerators) is a joint US-Japan investigation.

1991
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.

1994
Tsunami earthquake observation
instruments were delivered to JMA.
In light of the lessons learnt from the disastrous experiences in the Nihonkai-Chubu Earthquake and Southwest-off Hokkaido Earthquake (Okujiri Earthquake), Meisei’s tsunami earthquake observation instruments were deployed at 182 locations throughout Japan in order to detect earthquakes which may cause Tsunami as early as possible. These instruments allow around-the-clock observation of earthquakes throughout Japan and issue tidal wave information within approximately three minutes of the occurrence of an earthquake.

2000
AMOS
(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.

2003
“Hayabusa” was equipped with X-Ray Spectrometer (XRS).
This “Hayabusa” was equipped with X-Ray Spectrometer (XRS), which was developed by MEISEI.Measuring the fluorescent X-rays emitted from the surface of an asteroid, it is possible to determine about the type of element are there.

2005
“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.
2007
Technical contribution to Selenological and Engineering Explorer “KAGUYA”
Of the 15 observation missions of KAGUYA, Meisei took charge of 8 mission. In 2008, a Hi-Vision camera of Meisei successfully shot “Full Earth from the Moon.”
2012
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.
“WE WISH”
2014
Release of the world’s smallest and lightest iMS-100
Compared to conventional radiosonde devices, this global strategic product is a huge improvement in terms of miniaturization, lightness, safety, running cost and environmental load. A new type of sensor gives dramatically improved accuracy of observation.
“WE WISH”
“POTEKA®”
2014
“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.
