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).

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.
