Thailand Earth Observation System (THEOS): A New Dimension of Thailand Remote Sensing

摘要

Thailand has embarked in remote sensing activities for several decades. Over the past 20 years, the country has operated its own ground receiving station to acquire satellite imageries from various sources. The development of Thailand Earth Observation System (THEOS) Satellite brings a new dimension of remote sensing to Thailand. THEOS is a polar orbit, sun-synchronous satellite designed to provide operational remote sensing services to Thailand and worldwide. This paper describes THEOS background information and its characteristics including the satellite's bus, payload, orbit, imaging capacity and THEOS routine operation. The ground operations of THEOS including its ground control segment and image ground segment are also illustrated. Programmes associated with THEOS including capacity building, data applications promotion and international cooperation development are described.
