Problem statement. Nowdays all types of medium-altitude orbit spacecraft (SC) Glonass with an average orbit height 19 100 km are equipped optical retroreflector systems, which provide reflection of laser radiation from satellite laser ranging (SLR) station to the direction of the receiving telescope of SLR station. To improve the accuracy of the navigation field in the northern latitudes of the Earth the high-orbit spacecraft Glonass-VKK with an average orbit height of 36 000 km is developed in JSC “Information satellite systems named after M.F. Reshetnev”. In this regard, an urgent task is to obtain the accuracy and energy characteristics of the optical retroreflector system for the high-orbit SC Glonass-VKK.

The goal of the work to determine the accuracy, weight, size and energy characteristics of the optical retroreflector system for hegh-orbit spacecraft “Glonass-VKK”

Results. The accuracy, weight, size and energy characteristics of the optical retroreflector system for the spacecraft "Glonass-VKK" are given. An assessment of the characteristics of the optical retroreflector system for the high-orbit spacecraft "Glonass-VKK" was performed, on the basis of which the possibility of obtaining averaged results of distance measurements between the SLR station and retroreflector system with a root-mean-square error of less than 1 mm was confirmed.

Practical significance. The results of the work will be used in the creation of the optical retroreflector system for the spacecraft "Glonass-VKK".
