G.I.Emeliantsev, O.N.Anuchin On shortening of the readiness time of shipborne inertial navigation systems 3
The article draws attention to the possibility of shortening the shipborne INS readiness time at the INS start out of the cold condition aboard a vehicle. The mode of precise alignment and calibration of INS is simulated as a filter problem solution. In the feedback a linear algorithm of the Kalman filter is used along with the installation of a heat mode system in the measuring module. Here non-stationary drifts of INS gyros are taken into account. Reference information is presented by data from SNS GLONASS/GPS about vehicle coordinates and linear speed vector components. The data are related to a point of INS measuring module location on the ship. The efficiency of this problem solution is shown in conditions of moving vehicle and at essential distance of INS measuring module position relative to the ship mass center.
V.M.Ambrosovsky, E.B.Kats, D.A.Skorokhodov Algorithm for providing the failproofness of hydrofoil motion control systems 11
Analysis of emergency conditions in hydrofoils is made. Possible anti-damage control algorithms for different types of accidents are considered as well as algorithms for detecting failures of data sen- sors. Results of algorithm simulation for ensuring the failproofness of automatic motion control systems are presented.
V.M.Korchanov, E.I.Veremei, V.V.Eremeev Synthesis of algorithms of submarine robust control nearby the rough sea surface 21
It is shown that the influence of free sea surface becomes rather essential with a certain diving depth that can result in loss of stability in a closed system. A method is developed for synthesis of robust stabilizing control with allowance for ambiguity factor at the submarine rise to the periscope depth. The corresponding calculation procedure is presented. A problem of synthesis of multipurpose stabilization algorithms is defined and solved. On the basis of this problem the structure of automatic control law for rudders is obtained providing the fulfillment of requirements to the dynamics of control processes.
V.I.Zarudny, M.S.Finkelshtein Multiple readiness function 30
A problem of multiple readiness factor determination is considered. This factor is a generalization of usual readiness coefficient. Exact and simple approximate expressions are derived which make it pos- sible to find a multiple readiness factor for different situations being of practical importance.

O.S.Salychev, V.V.Voronov, V.V.Lukyanov Inertial navigation systems in geodetic applications 37
The paper presents the work results of the Laboratory of Inertial Geodetic Systems in the Moscow State Technical University named after N.E.Bauman. This laboratory performs researches in the field of application of inertial equipment in geodesy and geophysics: from precise positioning to aviation gra- vimetry. A wide spectrum of test results is presented. The tests were carried out in different countries using our equipment and data processing algorithms.
Yu.A.Litmanovich, V.M.Lesyuchevsky, V.Z.Gusinsky Information processing using increments of signal multiple integrals: from strapdown INS to other real-time systems 46
A new approach to signal processing in strapdown INS (SINS) is presented. This approach can also be applied in other real-time systems. Three SINS problems that can occur in different systems were solved through the usage of increments of signal multiple integrals at a step of the problem solution. The authors made the analysis of possibility and expediency of generating signal multiple integrals during the preliminary data processing.
S.P.Dmitriev, O.A.Stepanov, B.S.Rivkin, D.A.Koshaev, D.Chang Optimal map-matching for car navigation systems 57
Within the scope of Markov nonlinear filtration theory the authors define and give the general solution for the problem of car positioning on the road in the presence of external data of coordinates, speed and heading and with the use of digital road map. The purpose of the problem is to find a more probable road along which a car moves and to determine its position on the road to the maximum accuracy. The authors suggest the problem solution algorithm and analyze a potential accuracy of the solution. An experimental examination of the developed algorithm is carried out with the use of real measurements of the satellite system and the road map data.
I.N.Beloglazov, S.N.Kazarin Stereoscopic systems of navigation and observation 70
Owing to the successful development of on-board digital computers new opportunities appeared for using stereo effect contained in images of different iconic systems. These new opportunities are considered in the paper. Possible solutions of various technical problems are discussed. The theory of stereoscopic navigation system precision is evolved and experimental researches of these systems are carried out verifying the basic theoretical conclusions.
