Abstract. A method of selection of the program of nanosatellites separation from an undirected space platform at the stage of a flight task formulation is proposed. The method is based on statistical researches and provides a predetermined character relative motion of nanosatellites. The choice of the nanosatellite separation parameters is based on the application of a criterion that describes the maximum distance between each pair of nanosatellites, with the exception of the possibility of their dangerous approach both with each other and with the platform from which they are separated. As a result, the separation parameters are selected, for which the maximum value of the distance between the nanosatellite is minimal and thus the flight safety is ensured. The method is demonstrated in details by the example of nanosatellites group separation from the orbital stage of "Soyuz" carrier rocket.
