The 100kg THEOS-2A satellite project for GISTDA (Thailand) centred around the transfer of knowledge to enable Thai engineers to design, manufacture, integrate, and test similar satellites in Thailand in the future.   A total of 48 Customer Engineers were involved in the programme over a period of four years, with training and mentoring taking place in the UK and in Thailand.  THEOS-2A  was SSTL’s 20th Know-how Transfer programme and our second collaboration with Thailand - we previously trained customer engineers during the 1995-1997 Thai-Paht mission.  
Unfortunately THEOS-2A failed to reach orbit due to an issue with the launch.

With funding from ESA's Scout programme, SSTL's HydroGNSS 2 x 55kg small satellites will take measurements of key hydrological climate variables, including soil moisture, freeze thaw state over permafrost, inundation and wetlands, and above ground biomass, using a technique called GNSS Reflectometry which exploits existing signals from Global Navigation Satellites, such as GPS and Galileo, as radar signal sources. These signals are reflected off the land, ice and ocean and can be collected by a low power receiver on a small satellite in low Earth orbit, and used to yield important geophysical measurements. HydroGNSS paves the way for an affordable future constellation that can offer measurements with a temporal-spatial resolution not accessible to traditional remote sensing satellites, thus offering new capacity to monitor very dynamic phenomena and helping to fill the gaps in our monitoring of the Earth’s vital signs for the future. The HydroGNSS mission will assist with the fight against climate change by providing valuable measurements using space technology.

We have supplied a Multi Spectral Imager (MSI) Instrument for the EarthCARE mission, ESA's third Earth Explorer Core Mission. The EarthCARE mission has been specifically defined with the basic objective of improving the understanding of cloud-aerosol-radiation interactions so as to include them correctly and reliably in climate and numerical weather prediction models. EarthCARE will meet these objectives by measuring simultaneously the vertical structure and horizontal distribution of cloud and aerosol fields together with outgoing radiation over all climate zones.

Built by Surrey Satellite Technology Limited (SSTL) for UK company Satellite Vu, HOTSAT-1 boasts a ground-breaking 3.5m resolution mid-wave infrared imager with astonishing video capability, all while maintaining a sensitivity of less than 2 degrees Celsius. This unparalleled satellite video generation capability enables the detection of highly dynamic features and the creation of 3D profiles, facilitating a multitude of applications. From mitigating the effects of heat islands in urban centres to monitoring industrial processes, waterway pollution, ensuring energy efficiency, and assessing the health of solar farms, HOTSAT-1 is set to transform industries across the globe.
 

SSTL supplied the Client satellite and avionics for ASTROSCALE's inaugral ELSA-d mission, which will simulate capture of orbital debris and is designed to validate key technologies for end-of-life spacecraft retrieval and disposal services.  

The ELSA-d mission comprises of a "Servicer" satellite and a Client (target) satellite, and will demonstrate key technologies necessary for orbital debris removal such as rendezvous and docking and proximity operations.  ASTROSCALE are designing and manufacturing the Servicer satellite in Tokyo using avionics from SSTL.
