MISSIONS IN BUILD

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. As early as Q4 2022, 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.

THEOS-2 SmallSAT

The THEOS-2 SmallSAT project for GISTDA (Thailand) is centred around 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.

ELSA-d Target

SSTL is supplying a "Target" 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 "Chaser" satellite and the 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 Chaser in Tokyo using avionics from SSTL.

Galileo Navigation Payloads

We have already delivered 22 navigation payloads for the deployment phase of Galileo, Europe's satellite navigation system and are now under contract to build a further 12 payloads.

OHB System AG is the prime contractor and builder of the spacecraft platform and SSTL has full responsibility for the navigation payloads, the brains of Galileo's navigation system.

Orbital Test Bed - OTB-2 & OTB-3

SSTL is supplying sets of avionics to General Atomics Electromagnetic Systems Group for the OTB-2 and OTB-3 hosted payload missions.

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.

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.

EUTELSAT QUANTUM

We have supplied a small geostationary satellite platform for the first “EUTELSAT QUANTUM” class telecommunications spacecraft.  We are under contract to prime contractor, Airbus Defence and Space, who are supplying the flexible payload for the spacecraft.  

EUTELSAT QUANTUM will be SSTL's first geostationary satellite platform and the new spacecraft design will represent a first in the commercial satellite industry, by enabling the complete electronic synthesis of “receive” and “transmit” coverages in the Ku-band. 

EarthCARE

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