Development of the TRSSS-1 Satellite as the Major Component of the Space Based Information System(SBIS) for Effective Decision Support System for Thailand's Natural Resources and Environmental Management

The paper describes development of the first Thailand Remote Sensing Satellite System (TRSSS-1) by the National Research Council of Thailand (NRCT), Ministry of Science Technology and Environment (MOSTE). The TRSSS-1 project has primarily been developed as a major component of the Space Base Information System (SBIS) for effective decision support system for Thailand's natural resources and environmental management. The Space Based Information System consists of three components namely, the up-stream component, the interfacing component and the downstream component. The up-stream component consists of the Space Segment and the Ground Segment [consisting of the Mission Control Center (MCC) and the Data Acquisition and Processing Facility (DAPF)] and the Launch Segment. The interfacing component consists of telecommunication and associated Hypertext based user interface communication and software. The down-stream component consists of space based industries, human resources development, technology transfer and development and applications of space based information network for effective decision support system for natural resources and environmental management for Thailand and her neighboring countries in ASEAN and Asia region and globally. The spacecraft bus and instruments are described. The optical instruments including electronics are also presented. The TRSSS-1 program has already been approved by the previous Royal Thai Government in 1996 and the required budget provided. The development period takes about 36 months with the target launch date towards midyear of the year 2000.
