First of two weather satellites to be fully operational in 2015
Himawari Operation Enterprise Corporation (Himawari Operation
Enterprise) and Mitsubishi Electric Corporation (TOKYO:6503) announced
today the completion of the ground operations system for the Himawari-8
and Himawari-9 weather data transmission satellites. The Japan
Meteorological Agency (JMA) plans to launch Himawari-8 and -9 in Summer
2014 and 2016, respectively, to enhance public safety and security
through relaying sophisticated weather data contributing to disaster
prevention and monitoring global environment.
The ground operations system designed, built and installed by Mitsubishi
Electric consists of antennas with a 9-meter diameter and radio
frequency and satellite control equipment installed at the main unit in
Hiki-gun, Saitama Prefecture, and the sub unit in Ebetsu, Hokkaido.
Through their involvement in weather satellite operations, the two
companies will continue to contribute to disaster prevention and
monitoring global environment.
1)Double redundant configuration for stable and
A two-unit operation scheme ensures stable and consistent observation
data transmission to JMA. Each unit features a redundant configuration
including antennas with a 9-meter diameter.
2)Timely retrieval of observation data
Thanks to the systemís alignment to the geographical coverage area of
Himawari-8 and -9, observation data can be retrieved once every 2.5
minutes (up to 576 times per day), enabling the provision of
up-to-the-minute information on typhoons, rainstorms and other climatic
anomalies by geographic sector. Previously, data retrieval was limited
to once per day.
3)Cutting back on labor
The introduction of an integrated system simultaneously monitoring the
two satellites and both ground units enables manpower to be reduced over
a 15-year period.
Himawari Operation Enterprise and Mitsubishi Electric will soon begin
comprehensive system tests and personnel training for satellite
operations for Himawari-8 under the supervision of JMA.
Mitsubishi Electric, which is contracted by JMA to build and deliver
Himawari-8 and -9, received the manufacturing order for antennas with a
9-meter diameter, radio frequency equipment and satellite control
equipment from Himawari Operation Enterprise in September 2010.
