Project TYCHE

SSTL is building a 150kg satellite based on SSTL’s Carbonite+ for UK Space Command. Project TYCHE is the first satellite procurement for the MINERVA programme which is a key enabler in the development of the foundation for a UK Space-based Intelligence Surveillance & Reconnaissance (ISR) constellation under programme ISTARI.

SatelliteVu MWIR Pathfinder

SSTL is building a Mid Wave Infra-Red (MWIR) thermal imaging satellite for Satellite Vu. The pathfinder satellite will pave the way for a planned constellation of MWIR spacecraft which will have the ability to measure the heat signature of any building anywhere multiple times a day, enabling SatelliteVu to derive new insights in real time about building emissions, energy use and insulation.

HydroGNSS

With funding from ESA's Scout programme, SSTL is building HydroGNSS, a 55kg small satellite to measure climate change variables.  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 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.

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.

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 2025, 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.

DarkCarb MWIR Imager

Leonardo and Surrey Satellite Technology Ltd have been awarded funding from the UK’s Centre for Earth Observation Instrumentation (CEOI) to develop a new detector assembly for a low cost, world-leading Mid-Wave Infra-Red (MWIR) imager.  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.

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.

Orbital Test Bed - OTB-3

SSTL is supplying sets of avionics to General Atomics Electromagnetic Systems Group for 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. 

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.

EarthCARE

We are supplying a Multi Spectral Imager (MSI) Instrument for the EarthCARE mission, ESA's third Earth Explorer Core Mission.
