Abstract
Thailand Earth Observation System (THEOS) Development Program was begun in July 2004. The program is developed by Geo-Informatics and Space Technology Development Agency (Public Organization) (GISTDA) under the Ministry of Science and Technology, with European Aeronautic Defence and Space Company – Astrium (EADS Astrium SAS), in France, as a prime contractor. It consists of design, development, test, launch, and commissioning phases of THEOS satellite, as well as integration with associated control and data exploitation ground facilities. This paper gives an overview of system architecture, satellite architecture, its performance and main applications, as well as technology transfer and trainings for Thai engineers and operators. THEOS satellite is a compact and agile satellite with a mass of 750 kilograms and a power consumption of 800 Watts. It has two push-broom scanning optical instruments, providing worldwide imagery in Panchromatic and Multispectral modes, covering the Visible and Near Infrared spectrum. The Panchromatic instrument has a resolution of 2 metres and a swath width of 22 kilometres. The Multispectral instrument has a resolution of 15 metres and a swath width of 90 kilometres. The satellite will be launched into a sun-synchronous low earth orbit in July 2007 and will have a design lifetime of at least 5 years. 1. Introduction After many years of using remote-sensing data from foreign satellite systems, Thailand has decided to have its own earth observation satellite system for rapid and sustainable country development.
