Before we can ask ‘how will it work?’ we need to define exactly what we want to achieve.
There are two sets of performance criteria – ideal and minimum. The minimum performance criteria will achieve the artistic goals of the project. Reaching the ideal performance criteria would make Orbital Illumination suitable for the greatest range of commercial and emergency applications.
We provided both sets of criteria to give researchers contextual goals when recommending particular technologies or solutions. Certain trade-offs may be acceptable within the context of the entire project.
- High Global Availability – Using a combination of satellites we can illuminate a target almost anywhere on earth with little notice.
- Smooth and steady beam – Highly controlled beam movement
- Searchlight brightness – Brightness comparable to a modern searchlight
- Real-time control – We can steer a beam live from the ground
- Narrow beam – 30m diameter or less at surface
- Camera – For search and rescue applications a camera would be able to relay images of persons arriving at the illuminated site
- Compact and lightweight – Nano form factor.
- Uses standardised components
- Planned Availability – All illumination tasks must be planned well in advance and are limited to selected geographic areas.
- Full moon brightness – Maximum brightness is comparable to the full moon
- Communication in limited windows – Tasks must be uploaded in advance
