Abstract
Space applications and use of satellite data became an important tool for production and development of many companies and institutions, as well as indispensable part of our daily lives, when using e.g. satellite navigation or TV broadcasting. Proper functioning of those services, however, requires the security of space assets at the orbits, their ground stations and the transmition links.
The basic threat for space assets is the growing number of debris at the orbits. Space Situation Awareness has a growing importance and sharing information among all main space actors becomes a pre-requisite.
Efforts to agree on common guidelines to mitigate possible risks related to outer space activities are made both within the UN and the EU as well as among all space agencies.
