There were 123 participants from 12 countries attending the workshop (Russia, France, Germany, Great Britain, Spain, Italy, the Netherlands, Japan, the Czech Republic, Turkey, Algeria, and Nigeria). Russia was represented by 98 participants (4 academicians, 3 corresponding members, Russian Academy of Sciences, 38 doctors of technical sciences, professors, 26 candidates of technical sciences, associate professors, 8 postgraduates, 19 researchers of the RAS, universities and aerospace specialists), including 23 members of the Academy of Navigation and Motion headed by the RAS Academician V.G.Peshekhonov, President of the Academy of Navigation and Motion Control.

The IFAC workshop was opened by the academician of RAS, A.B.Kurzhanskiy, Chairman of the Russian National Committee of Automatic Control. In his speech he mentioned the importance of conducting the IFAC event in Samara after the IFAC events in two Russian capitals (Saint-Petersburg, 2004, 2007; Moscow, 2009) and presence of the IFAC Technical Committee on Automatic Control in Aerospace leaders and well-known scientists and specialists on control in aerospace systems. The choice of Samara can be explained by a high scientific and practice potential of Samara scientific-technical aerospace cluster and vital necessity of developing international scientific relations.

Details, including the technical program, can be seen on the website of the AGNFCS-09 ( http://www.ssc.smr.ru/agnfcs09.htm ). The English language was taken as an official one according to the IFAC rules.

The practical achievements and lines of advanced researches in the sphere of rocketry, space exploration, and Earth observation spacecraft of the SRP RSC "TsSKB-Progress", a leading Roskosmos enterprise, were presented in the plenary paper "The SRP RSC "Trends and Future Prospects" by A.N.Kirillin, general director, R.N.Akhmetov, designer general, and S.I.Tkachenko, deputy designer general. Also presented were the results of international cooperation including numerous launchings of the Soyuz spacecraft and the Progress cargo spacecraft using contemporary modifications of the R-7 rocket family (designer D.I.Kozlov) to the International space station.

The plenary paper of G.P.Anshakov, the SRP RSC TsSKB-Progress deputy designer general and the CSRI Elektropribor researchers - V.G.Peshekhonov, general director, and B.Ye.Landau, L.P.Nesenyuk, heads of departments "Autonomous Attitude Reference System for Remote Sensing Satellites" was presented by V.G.Peshekhonov, the RAS Academician. In this paper, the analytical survey of the state-of the-art of the problem under consideration was well combined with presenting the scientific and technical solutions and practical results obtained by the CSRI Elektropribor in constructing an autonomous system on the basis of electrostatic gyroscopes for determining attitude reference of the Earth remote sensing space satellites.

Of considerable interest was the plenary paper "Networked Distributed Pico-Satellite Systems for Earth Observation and Telecommunication Applications" delivered by K.Schilling, Germany. The author presented both the theoretical problems of determining the current position of pico-satellites (with mass up to 1 kg) in the networked orbital distributed systems, problems of complex processing of received data and the practical results obtained by the International program supported by the European Space Agency.

The plenary paper "Nonlinear Dynamics of the Spacecraft Gyromoment Control System with Plasma Thrusters at Initial Modes" of V.A.Rayevsky, G.P.Titov, and Ye.N.Yakimov (Reshetnev Information Satellite Systems Company) and Ye.I.Somov (Samara Scientific Center) started with demonstrating a video film that presented the main achievements of the ISS Reshetnev company, a Roskosmos leader in development, manufacture and operation of telecommunication, geodetic and navigation satellite systems. Further, the company achievements concerningљ the guidance, navigation and control systems of spacecraft motion were concretized. Also given was the novel solution of spacecraft re-spin up by the weak internal moments of four gyrodines. The theoretical substantiation of nonlinearљ law for gyrodine control was performed based on the Lyapunov functions with the analytical proof of the uniform exponential stability for the required SC body rotation relative to the axis with the maximal value of the inertia moment. In conclusion, the results of computer simulation and animation of a flexible spacecraft spatial motion with the synthesized digital control law by gyrodines were presented in details.

In the paper of R.N.Akmetov "Problematic Points regarding Autonomous Functional Control of Low-orbit Remote Sensing Satellites" there were presented both the general approaches to solving problems of in-flight calibration of onboard measuring instruments, autonomous provision of reliability and survivability of SC control systems and the original scientific technical solutions realized aboard the Resurs-DK1 observation satellite.

An analytical survey of both the well-known and developed by the authors approaches to modeling the motion of large space structures, including in-orbit assembled ones and the novel methods of adaptive control of such structures motion was presented in the plenary paper by V.Yu.Rutkovsky, V.M.Sukhanov, S.D.Zemlyakov, and V.M.Glumov "Adaptive Control Systems of Large Space Structures with Variable Parameters".

At the instance of the authors G.Bertoni, P.Castaldi, N.Bertozzi, M.Bonfe, S.Simani (Italy) their plenary paper "Guidance and Nonlinear Active Fault Tolerant Control for General Aviation Aircraft" was presented in the brief form by Ye.I.Somov. The lecturers arrived in Samara by air, but could not pass border control because of an incident at drawing up the visa. Owing to these circumstances, the additional plenary paper "HTHL launch vehicles: concepts, advantages and control problems" was presented by A.V.Nebylov, Director of the International Institute of Advanced Aerospace Technologies,љ Saint-Petersburg State University of Aerospace Instrumentation.

K.Schilling (Germany) in his second plenary paper "Results from the Cassini/Huygens Space Mission to Explore the Saturnian Moon Titan" presented the final results of a unique long-term mission both as a precise technique of SC Motion control and the scientific data obtained and processed in NASA and ESA.

Ye.I.Somov in his plenary paper "Precise Guidance and Attitude Control Systems for the Information Satellites: Results and New Challenges" presented some results of the numerous research projects carried out in Department "Guidance, Navigation and Motion Control" of research institute on Mechanical Systems Reliability (Samara State Technical University) and the Dynamics and Motion Control Department, Samara Scientific Center, in cooperation with the JSC "ISS Reshetnev" Company and the SRP RSC "TsSKB-Progress". Particular attention was given to the effective algorithms of multiple filtration and gyromoment control realized aboard communication and observation satellites. The lecturer formulated the approaches to solving the topical problems on precision flight calibration of onboard measurement systems.

Finally, the planned panel discussion was held on the theme "Problems of Automatic Control at Developing of Advanced Aerospace Objects and Systems".

The workshop proceedings in English were published electronically in December 2009 and are available at website http://lib.physcon.ru in the electronic library of the International Physics and Control Society (Saint-Petersburg). All the presented papers will be electronically available on the IFAC website http://www.ifac-papersonline.net.

Besides the challenging technical program, the workshop included a nice array of social activities. Participants could enjoy a visit to the Aerospace Museum of Samara.

The IFAC Technical Committee on Automatic Control in Aerospace noted the high scientific and organizational level of conducting the workshop. Some papers were recommended to publishing in the IFAC official journals. We are sure that the workshop was an excellent forum for fruitful discussions and future international research cooperation regarding many topics related to aerospace guidance, navigation and flight control systems.

The next 18^th IFAC Symposium on Automatic Control in Aerospace will be held in Japan, September 6 - 10, 2010, http://www.space.t.u-tokyo.ac.jp/aca2010.
