Motivation & ObjectiveWhy Ground Station Network (GSN) is needed?• For Project Operation
5 satellites will be on-orbit in 2013Limited human resouce
• For Practical Use of micro/nanosatellitesLonger communication time (increase of data downlink)Keep backup ground stationEasy and cheap access to satellite for newcomers
What is the purpose?• To connect ground stations easily and quickly when it
is needed

Implementation plan for GSN development
• Share common view for required functions of GSN
• Architecture Ground Station Network which issuitable for micro/nanosatellite operations
• Define interfaces
• Kick-off meeting : June 2011 (TBD)

Summary
•
Micro/nanosatellite project is very active in manycountries
• Ground Station Network (GSN) is needed forp ractical Use of micro/nanosatellites
Easier and quicker establishment of connectionbetween ground stations is preferred
• More discussion is needed for GSN development
