CubeSats – useful applications
• Education and training (100%)
• Technology demonstrators (33%)
• Earth observation and remote sensing (18%)
• Space weather research (25%)
The percentage gives the proportion of missions launched by 2008 (from www.clyde-space.com).

Future nano-sat missions
• Nano-satellite constellations provides a paradigm shift from existing platforms:– High temporal resolution / medium ground
sampling resolution• 30 min / 20 m vs. 8 hours / 10 m
– Shift in applications– Technology threshold low– Can be done by Africa, for Africa, in collaboration
with our international partners
• Services• Disaster monitoring
• Quasi-real-time monitoring of flooding, veld fires, mud slides, etc.• Resource Management
• Water Management• Deforestation• Evaporation of lakes• Tracking animals (Big 5)• Crop yield and quality• Ocean temperature• Town planning and land management• Smart grid management for power utilities
Future nano-sat missions
• Services• Security/tracking
• Low-cost tracking of vehicles, assets, etc• Tracking boats - especially in view of piracy off the east coast
of Africa• Tracking trains
• Amateur payloads• Low bit rate services to isolated villages, communities• Awareness• Education and training
• Telemedicine• Low bit rate services

• Working Group in African Space Strategy and Policy
• African Union Commission is committed to promote elements of human
intellectual development, encourage technological and scientific leadership
and inspire young generations in Africa.
• ARMC agreement between South Africa, Kenya, Algeria and Nigeria, has put
Africa firmly on the path of developing home-grown satellite technology and
applications resources.
