How does space surveillance need to be improved in the future?
First of all, one should reach some level at which our knowledge on situation in space would be equal for all types of orbit to at least current LEO ‘completeness’ level from the point of view of estimated objects size. This will permit to construct much more accurate picture of the evolution of whole space debris population, to identify yet unknown sources producing space debris on different orbits and thus to correctly estimate possible quantity of still undetected space debris objects. In order to do this special worldwide distributed network of optical instruments (capable to observe objects on LEO, MEO, HEO and GEO) and maybe radars like the US Air Force Space Surveillance System (AFSSS, radar fence earlier known as NAVSPASUR) should be developed. In fact, existing astronomical facilities can be used for placement of special telescopes devoted to observation of space debris objects. There is nothing impossible in this idea if one takes into account existing worldwide network of hu
