Earth Observation Spacecraft

CARBONITEEarth Observation - Optical, HD colour video

Low cost 1m GSD colour video

Operating at an altitude of 500km, Carbonite satellites provide 1m GSD colour video employing a Forward Motion Compensation (FMC) imaging mode which enables captures of  >120 seconds of a single target, adding a new dimension to high resolution Earth observation imagery.

Carbonite-1, launched in July 2015, demonstrated low cost, 1m GSD imagery and was followed by Carbonite-2 in January 2018 which provided the world's first commercial HD colour video from space.


  • Change detection
  • Pattern of life assessments
  • Humanitarian and disaster management
  • Global high resolution situational awareness
  • National security
  • Elevation model generation
  • Infrastructure and asset monitoring

A constellation of Carbonite satellites would provide robustness against weather conditions and target concealment.

PRECISIONEarth Observation - Optical, Multispectral

Multispectral imager, with high agility and high area coverage

The SSTL-Precision satellite provides very high resolution, high quality imagery in support of pan-sharpened colour mapping and surveillance applications. The spacecraft is designed to be compact in order to support affordable operations as a stand-alone unit or in constellations providing higher temporal resolution. Larger than the Carbonite high resolution imaging spacecraft, it provides higher resolution data as well as signifcantly greater data return.

DARKCARBEarth Observation - MWIR

High resolution mid-wave infra-red (MWIR) imager

DarkCarb is a high resolution mid-wave infra-red (MWIR) imaging satellite which can produce thermal data with a resolution as good as the capability, with one tenth the spacecraft mass.


  • Change detection & human activity
  • Pattern of life assessments
  • Humanitarian & disaster management
  • Global high resolution situational awareness
  • National security & defence
  • Infrastructure & asset monitoring
  • Urban heat mapping

Lunar Communications SpacecraftLunar Comms

The SSTL Lunar Communications 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 first 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.
