Aerospace Instrument-Making Annotation << Back METHOD FOR MEASURING THE CURRENT NAVIGATION PARAMETERS OF SPACE OBJECTS IN THE NEAR SPACE ZONE А.K. Klyuchkin, E.V. Slatova, S.Yu. Baluev, A.V. Salychev The problem of measuring the current navigational parameters of the movement of space objects with the help of on-board optical-electronic means, which are equipped with spacecraft for monitoring the situation in near-Earth outer space, is considered. A technique for measuring the current navigation parameters of observed space objects by the method of space triangulation is considered. A feature of onboard optical-electronic means is the measurement of the angular coordinates of not only space objects, but also the angular coordinates of stars. On the basis of the method of measuring the current navigation parameters, numerical modeling was carried out and the parameters of the orbit of the observed space object in the near space zone were calculated. The obtained results of modeling the measurements of current navigation parameters and calculations of the parameters of the orbits of space objects can be used in research and development work on the development of an orbital constellation of space observation spacecraft, as well as in the evaluation of algorithms for measuring current navigation parameters.
