We present the full cycle review carried out for closed and simulating operations of active spacecraft from rendez-vous to docking or capturing of a passive object, including simulating stands created by world space companies. The rendez-vous of spacecraft becomes one of the most used and at the same time the most complex and responsible operations in space. The systems being developed today are aimed at accomplishing the rendez-vous tasks of non-cooperative rotating objects. They should provide collision avoidance and possible further trouble-free mooring (capture, docking). The rendez-vous control system is becoming one of the most responsible, complex, and expensive spacecraft systems. The increasing complexity and responsibility of rendez-vous systems make new demands on their ground-based experimental development and testing. The characteristics of the JSC "RPC KURS" and PrJSC "ELMІZ" operating stand obtained in electrical and mechanical tests of the mutual measurement system equipment are given.
            A comprehensive stand for testing mutual measurement systems is not only a tool for research and development of new ones but also serves the mass production of these highly complex systems. The hardware staffing of the stand allows the development of radio and optical sensors of the mutual measurement system for the rendez-vous of two cooperative objects and for the rendez-vous of two non-cooperative objects. Composition, configuration and operating algorithms of the simulation stand for testing systems which use different sensors for mutual measurements of position and parameters of active spacecraft motion performing rendez-vous maneuvers and passive object have been considered. The scheme of the stand for tests of the optical measurement system is given.
