THEOS-2A Satellite

THEOS-2A, a 100 kg satellite class, co-develop by Geo-Informatics and Space Technology Development Agency (GISTDA) and Surrey Satellite Technology Limited (SSTL). The satellite is capable of capturing high-resolution imagery and footage which is perfectly fit for disaster monitoring, agriculture, and urban planning applications. Furthermore, this mission offers a first-ever end-to-end satellite development and technology know-how transferring to Thai people aiming for building a space ecosystem and capability in Thailand. 

This program also includes an in-country manufacturer promoting scheme and a space infrastructure development program that will pave a way for Thai-made space technology and activity in the future which is now successfully proven and received an enormous attraction and create a space technology awareness among Thai society.

Know-How and Technology Transfer

The Theos-2A project focus on the transfer of knowledge to enable Thai engineers to design, manufacture, integrate, and test similar satellites in Thailand in the future. Thai engineers involve the program for 4 years with training and mentoring taking place both in the UK at SSTL’s Guildford facility, and in GISTDA Space Krenovation Park  Thailand.  

  • 22 Thai engineers work along with SSTL engineers to co-design, develop, build, and test the THEOS-2A satellite
  • Build the experimental payload on the THEOS-2A satellite comply with  European Space Standardization
  • Support in-country manufacturing and Thai satellite capacity building
