Background of CBMS Plan

• Communications and Broadcasting
• Increase of satellite communications and
  broadcasting service demands in Korea.
• Development of the next generation payload
  technology on satellite communications and
  broadcasting.
• Meteorological Observation Demand
• To minimize damage from meteorological disasters
  by adequate preparation.
• Needs on accurate prediction of local severe
  weather activity in Korea.
• Oceanic Monitoring Demand
• Preservation of ocean resources by real-time
  oceanic information.

5
Mission Concept of CBMS

• Accurate observation of local severe weather
  activities.
• Ocean monitoring around the Korean peninsular.
• Improvement of short/long-term environment
  forecasting.
• In-orbit verification of developed communications
  and broadcasting transponders

6
CBMS Meteorological Mission

• High resolution image acquisition
• Offering the special observation mode for local
  severe weather watch
• Detection of typhoon, heavy rain, air pollution,
  yellow sand, natural phenomena, and etc.
• Vertical atmospheric measurement by Sounder

7
CBMS Oceanic Mission

• Efficient management of sea resources
• Environmental observation around the Korean
  peninsular
• Ocean color monitoring
• Sea surface temperature measurement
• Data collection of the ocean by means of buoy

Summary

• The CBMS is the 7th national satellite project in
  the series of Korea space development plan.
• The purpose of CBMS is
• To fulfill the demands of the public
  communication, weather forecasting and ocean
  monitoring.
• To advance the space technology by utilizing the
  experience from Koreasat and KOMPSAT programs.
• The development plan is under consideration to
  cooperate with foreign space-related companies to
  increase the reliability of the first CBMS flight
  model.
