Radiation Analysis Services Ltd (RASL)

Radiation Analysis Services Ltd is a United Kingdom consultancy that specialises in space environment radiation effects. The company supports satellite and equipment manufacturers with radiation analysis and assurance at component, equipment, and satellite level. It works with projects ranging from NewSpace ventures to full ECSS and military programmes.

RASL works with a wide range of clients from small start ups to large prime contractors across the world. The company has provided radiation hardness assurance for more than 80 missions and has supported over 60 customers globally since its founding in 2016. This broad experience covers low Earth orbit, geostationary, and deep space missions. Customers include major aerospace groups, university research departments, and emerging space companies.

The consultancy offers mission radiation environment modelling, total ionising dose analysis, total non ionising dose analysis, and single event effects analysis and mitigation. It also provides radiation hardness assurance, radiation test planning, and guidance on component selection including trade offs between commercial off the shelf and rad hard parts. RASL delivers informed guidance on the most useful radiation testing to perform and design mitigation options for single event effects. Shielding options for cumulative radiation effects are also evaluated.

RASL conducts spacecraft surface and internal charging assessments, atomic oxygen erosion analysis, and solar cell degradation studies. The team reviews equipment bills of materials and declared component lists, and prepares detailed radiation analysis reports for projects. It can also perform retrospective in orbit anomaly investigation when heritage designs are used in new environments. Training in radiation effects and assurance is available for project teams.

The company has supported projects spanning NewSpace, full ECSS, and military standards. Its project experience includes missions such as Galileo IOV and FOC, NovaSAR, Quantum, ExoMars, Inmarsat 6, Sentinel 1, MetOp, Solar Orbiter, Comet Interceptor, EarthCARE, TANGO, ARIEL, the Gateway ERSA payload, and the Canadarm3 pan tilt unit. It has also supported ESA missions from Class I to Class IV along with numerous nanosatellite and cubesat developments. Other work includes the Deep Space Gateway, Lunar Trailblazer, TRUTHS, ELSA D, and ELSA M missions.

Beyond full project work, RASL supports bids and proposals with expert radiation input. It also assists end customers with mission radiation requirements, radiation environment definition, and radiation control board reviews. Initial discussions regarding needs and scope are offered without charge.
