At present day, many modern navigation and geodesic spacecraft equipped with a so-called retroreflector arrays (RA). The purpose of such RA is a reflection beam of laser rangefinder to precisely measure distance to the satellite and clarify the parameters of laser rangefinder. To achieve the required energy and accuracy characteristic, it is necessary to provide optimal far field diffraction pattern of reflected radiation by construction of RA. By increasing the number of cube corner reflectors (CCR) increases the equivalent scattering surface (ESS) and probability of reflection radiation from two or more CCR. An important task of improvement of RA is minimizing of random measurement error range associated with reflection of the laser light from two or more CCR. In this paper we consider small size RA for low-orbit satellite. We performed a theoretical calculation of the energy characteristic of the laser radiation reflected from RA at a different position of satellite on the celestial sphere. The value of the random measurement error RA calculated. Relatively small size of CCR and designed features of RA minimize the weight of device and provide the requirement determination of range to low-orbit satellite with value of random measurement error distance less than 1 mm.
