  1. GCOM status Keiji Imaoka Earth Observation Research Center Japan Aerospace Exploration Agency AMSR-E Science Team Meeting July 2008 Telluride, CO

  2. GCOM 1st generation GCOM-W1 (Water) GCOM-C1 (Climate)

  3. GCOM Status • Satellite system • GCOM-W1 • Development of satellite: Phase-C • Development of AMSR2: Phase-C to D (under review) • GCOM-C1 • Now in Phase-B, waiting for phase-up review • Ground segment • GCOM-W1:Completed SDR and preparing for RFP

  4. GCOM Status • Science • GCOM 1st Research Announcement • Issued: Jan. 2008. Proposal due: Apr. 2008. • Selection of PI has already finished. • Cooperation between US-Japan is under discussion. • Workshop is currently scheduled in Jan. 2009. • Future • GCOM 2nd RA for GCOM-C1 is scheduled to be issued in this JFY, but will depend on project and budget condition. • Discussions began for GCOM-W2.

  5. Sensor Unit Control Unit AMSR2 Instrument Deployed Stowed Channels in 7.3GHz band for possible RFI mitigation. Two MWAs in control unit and mission module for redundancy. Improvement of HTS (warm load).

  6. Heat supply from HTS wall heaters Absorption material Heat supply from TCP Rotation center Rotation center Cutout for feed horns Heater Temp. monitor TCP AMSR sensor unit AMSR2 sensor unit Surface: MLI HTS design changes • Improvement of HTS • Change of heat control methodology • Thermal Control Panel (TCP). • Controlling heat of TCP and HTS case structure. • Blocking of thermal coupling between HTS and its outside. • Change of temperature monitoring (e.g., number of points, vertical distribution). • No change for absorbing material itself. Heat control of AMSR/HTS Heat control of AMSR2/HTS

  7. SGLI Instrument
