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]
THEOS-2, along with the THEOS-2A Smallsat, is part of the GISTDA's Development Survey Satellite System Project (โครงการระบบดาวเทียมสำรวจเพื่อการพัฒนา).[5] [6] Following THEOS-2, Thailand intends to build the THEOS-3 satellite completely domestically.[7]
