1 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. KITSAT Series

12 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 Satellite (< 500 kg) Trend

14 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 Small EO Satellite Applications

Urban Planning Disaster Monitoring Land Management Seashore Monitoring Crop Management Many More… 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 Conventional and Small Satellites

Traditional EO Satellites

Complementary

Conventional High Quality Image EO Satellites

Data Freshness Small EO Satellite & Timeliness Constellations 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
