Survey of geostationary objects with photographic observations performed at two stations - orbits evolution and probabilities of collisions -

The possibilities of survey photographic observations of geosynchronous satellites from two stations and their identification are given. A distribution of a semi-major axis changes of the geosynchronous satellites in time of their launch are represented. The ways of calculation of probability of satellites collisions with other objects on geostationaries orbits especially in "collocate" zones are outlined.
