THEOS-2 (Thailand Earth Observation System-2), is a Thai Earth observation satellite. The satellite would be capable of observing Earth's surface with a resolution of up to 50cm, and covering about 74,000 square kilometers per day.[1] THEOS-2 was launched by a Vega rocket from Guiana Space Centre in French Guiana on 9 October 2023.[2][3][4]
The THEOS-2A small satellite, lost in the PSLV-C62 launch accident in 2026,[5] was planned to be part of the GISTDA's Development Survey Satellite System Project (โครงการระบบดาวเทียมสำรวจเพื่อการพัฒนา) together with THEOS-2.[6][7] Following THEOS-2, Thailand intends to build the THEOS-3 satellite completely domestically.[8]
