BackForward Satellite Programme: Himawari 3rd generation 

Programme details
Programme description
  • Series of 2 operational meteorological satellites in geostationary orbit.
  • Follow-on of the 2nd generation Himawari based on MTSAT satellites.
  • Main developments: mission no longer shared with Transport, much improved imager enabling additional environmental applications
  • Programme managed by JMA.
  • The platforms are actively stabilised over 3 axes.
  • The design life time of the satellites is 8 years.
  • Nominal position around 140°E.
  • The replacement policy is based on one satellite in hot standby in a neighbouring position.
  • See detailed description at http://mscweb.kishou.go.jp/himawari89/space_segment/spsg_spacecraft.html
Data circulation
  • The raw data stream is transmitted to the CDAS (Command and Data Acquisition Station) using a Ka-band frequency in the range 18.1-18.4 GHz.
  • After pre-processing, the data are available via Internet/FTP,
  • A plan for data retransmission by a telecommunication satellite is being explored.
