Space Development
Conventional Satellite• Generally available only to developed countries in
space
Small Satellite• A feasible tool to access space for emerging
countries• Korea started space development with a small
satellite program by the university, KAIST, 20 years ago.

THEOS
Remote Sensing (Earth Observation)
International Activity• Initially available only to ‘super powers’, then to wealthy nations
From the 80s, • High resolution satellite imageries were commercially available
• 10 m resolution images were dominant in the market
From the late 90s, • 1 m resolution satellite imageries appeared
• Currently sub-meter class imageries available as well as moderate resolution with wider swath width
Conventional EO Satellites• Built by wealthy nations due to extremely high cost

Small EO Satellites
From the Early 90s,• Small satellite manufacturers started Earth observation missions
• The image qualities were not good enough for remote sensing applications.
From the late 90s,• Useful quality of 10 m resolution images were generated
Currently,• High performance small satellites that can generate up to 2.5 m
resolution images are available.
Small EO satellites • Developed with very low budget compared to conventional ones

Future Trend Expected
Demand for High Resolution Images ↑• To see the details
• Limited spectral channel
Demand for Wide Swath ↑• Due to frequent natural disaster.
• Various spectral channels

Concerns of Emerging Countries
Sustainable Space Program• Continuous support from government
• Political and social recognition
• Mission should be accepted beneficial to the people
• Technology acquisition• Mission considering requirements & constraints
A high performance and cost effective small Earth observation mission can be a good candidate
Concerns of Emerging Countries
Keeping the Trained Manpower after the 1st program
• Approval of mid- & long-term space development plan
• Let the team busy with satellite development• Make the team proud of themselves
Suggestion to Emerging Countries
1st Phase: Technology Acquisition• Acquire technology through joint satellite
development with an experienced partner• Manpower buildup
2nd Phase: Technology Verification & Enhancement
• Lead satellite development & enhancement
3rd Phase: Indigenous Model Development• Indigenous model development for future
missions
Conclusion
Space: Precious Asset • To be develop peacefully for the progress of
humanity & accessible by all
Space Development: International Activity • To be performed for the benefit of all nations• More number of active international cooperation
anticipated
