HydroGNSS 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 and 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. DISCOVER MORE THEOS-2 SmallSAT The 100kg THEOS-2 SmallSAT project for GISTDA (Thailand) is centred around the the transfer of knowledge to enable the Thai engineers to design, manufacture, integrate, and test similar satellites in Thailand in the future. A total of 48 Customer Engineers will be involved in the programme over a period of four years, with training and mentoring taking place in the UK and in Thailand. THEOS-2 SmallSAT is 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. DISCOVER MORE Lunar Pathfinder The Lunar Pathfinder spacecraft is designed to provide affordable communications services to lunar missions via S-band and UHF links to lunar assets on the surface and in orbit around the Moon, and an X-band link to Earth. Due to launch 2024, the Lunar Pathfinder spacecraft will be a mission enabler for polar and far-side missions, which, without direct line of sight of the Earth, would otherwise have to procure their own communications relay spacecraft. Lunar Pathfinder is a more cost effective alternative to Direct-to-Earth solutions and a credible alternative to institutional deep-space ground stations, offering orbiters and near-side missions a better availability, enhanced safety and improved data-rate.

The MWIR imager will be designed to achieve 3.5m GSD and to fit into a small and low cost agile platform with a launch mass of approximately 130kg to address the future demands of the evolving Earth Observation constellations market. View short video DISCOVER MORE Precision Multispectral Imager SSTL is manufacturing a new very high resolution imager that delivers high quality imagery and high area coverage for pan-sharpened colour mapping and surveillance applications. The Precision imager is a compact design that utilises a novel sensor and innovative opto-mechanical techniques to achieve a swath of >9.5km and a GSD in panchromatic channel of 0.6m native. The PAN channel is used to sharpen four 1.2m GSD multi-spectral channels and through post-processing sub 0.5m GSD is achievable. Precision’s detector is a novel CMOS-in-CCD architecture resulting in low power consumption and read noise and time delay and integration capability. Teledyne e2V is providing the state-of-the-art TDI CMOS sensor. SSTL is building the imager as part of ESA’s InCubed programme. DISCOVER MORE Orbital Test Bed - OTB-2 & OTB-3 SSTL is supplying sets of avionics to General Atomics Electromagnetic Systems Group for NASA's MAIA satellite and the OTB-3 hosted payload mission that will fly an Argos-4 payload. Self-aligning Deployable Space Telescope SSTL, the University of Oxford and the Surrey Space Centre have been awarded National Space Technology Programme funding to develop a novel self-aligning deployable space telescope, designed for sub 1 metre ground sample imaging requirements in a small launch volume spacecraft. The demonstrator telescope will release from stowed launch configuration, deploy to full length, and autonomously align ready for in-orbit acquisition. DISCOVER MORE Deployable SAR antenna payload SSTL and Oxford Space Systems have been awarded National Space Technology Programme funding to develop an innovative and stowage-efficient Synthetic Aperture Radar (SAR) payload. The innovative SAR payload will be exclusively developed in the UK and will comprise of a highly stowage-efficient deployable antenna from OSS and a high bandwidth radar instrument and RF system from SSTL. Successful completion of the project will enable the OSS antenna to be flown on a future demonstration mission from SSTL targeted for a 2021 launch. DISCOVER MORE EarthCARE We are supplying a Multi Spectral Imager (MSI) Instrument for the EarthCARE mission, ESA's third Earth Explorer Core Mission.
