<strong>THEOS</strong> SystemGISTDA has gained experience and expertise inSatellite Development from <strong>THEOS</strong> and moving from“Ground Station Operator and Data Provider”“Satellite Operator (including the operating costincreasingly) and the Data Provider for national andinternational users”
Conclusion• Space Technology and EO system become very important andbenefits not only to the country who develop EO system, butalso to other countries globally. <strong>Thailand</strong> has been gainingtechnological experience and expertise from <strong>THEOS</strong>. <strong>THEOS</strong>system shall be made useful for <strong>Thailand</strong>. It is possible to shareresources and experience with JPT members.• The numbers of activities can be shared among us.- Share Vision- Share Facility- Share Experience, Data, Information- Share Resource- Save the system development cost, operating cost and timeThis shall be beneficial to all members as a whole.
