Evaluating the safety of systems for lighting subpolar towns from orbit

Among major problems posed by the threat of predicted changes in the global climate in the 21st century is the problem of replacing hydrocarbon power with renewables. The use of space technology for solar insolation of the Earth surface can make a positive contribution to solving this problem, while at the same time contributing to preservation of the vulnerable environment of Polar regions. This paper discusses the safety of systems for illuminating from orbit subpolar towns in Russia and abroad. Based on the chosen safety criterion for a generic lighting system, its actual value was calculated and compared with established standards, and parameter association was provided for safe lighting system, that have orbital architecture and lighting patterns on the ground that are similar to those of the reviewed generic system.
