December 4, 2009. S.P.Korolev RSC Energia,
Korolev, Moscow region
S.P.Korolev Rocket and Space Corporation Energia held a session of the Corporation's Dissertation Review Board headed by the Chairman of the Corporation's Scientific Council, the full member of the Russian Academy of Sciences V.P.Legostaev.
Reviewed at the session were papers presented by employees of the Corporation:
M.V.Mikhailov - doctoral (Engineering Science) thesis on the subject of "Spacecraft (SC) Navigation, Attitude Control, and Rendezvous Based on Signals from Global Satellite Navigation Systems GLONASS and GPS";
A.S.Anfalov - candidate's (Engineering Science) thesis on the subject of "Dynamics of Separation of Rescue Vehicles from an Non-oriented and Non-stabilized Orbital Station".
The thesis by M.V.Mikhailov solves the scientific and engineering problem of developing methods and means of spatiotemporal support for controlling SC for various purposes using signals generated by global satellite navigation systems GLONASS and GPS. The scientific novelty of this paper consists in methods and algorithms which allow real-time generation of high-accuracy estimates of parameters of low-earth SC orbits, as well as methods for simulating high-order Earth gravitational field for use in on-board computers, for determining SC aerodynamic drag based on the navigation system measurements, for determining the SC attitude based on the measurements of asynchronous receivers, for solving the task of relative navigation during SC rendezvous at far and medium range, etc.
The practical importance of this work consists in improving the efficiency of space hardware by means of developing systems for spatiotemporal support for controlling orbital spacecraft for various purposes with higher accuracy and dynamic performance, while reducing their mass, power consumption and cost.
In the paper by A.S.Anfalov the Dissertation Review Board has noted the following most prominent scientific results: developing an approach to the study of rescue vehicle separation from an orbital station in cases of emergency crew evacuation; development of a math model for the separation process based on the modern theory of structurally complex mechanical systems and computational methods, development of methods and algorithms for safe SC separation from large space vehicles. The novelty of the results of this work stems from the uniqueness of the space station configuration discussed in it. This results can be used for future orbital station and spacecraft projects.
Based on the results of the review the Dissertation Review Board made the following decision:
- request that the State Commission for Academic Degrees and Titles confers on M.V.Mikhailov the academic degree of the Doctor of Engineering Science;
- confer on A.S.Anfalov the academic degree of the Candidate of Engineering Science.
