The problem of increasing the accuracy at estimating the inertial navigation systems errors by using identifying the parameters of the model is investigated. A scheme for correcting navigation systems with an estimation algorithm is presented. The accuracy of the errors estimation for the inertial navigation system by using the nonstationary adaptive Kalman filter when the average frequency of the gyroscope random drift changes is determined. A simple method for parametric identification of the change average frequency of a random drift by using a tuning coefficient is proposed. The results analysis of the estimation algorithm modeling by using the data of laboratory experiments with the serial navigation system Ts-060K is carried out. In the models of the estimation algorithm different average frequency values of the random drift change are used. Keywords aircraft; inertial navigation system; estimation algorithm; parametric identification; average frequency of random gyroscope drift; tuning factor; estimation accuracy

The basic operation principles of the strapdown inertial navigation systems (SINS) without platform and models of the measuring sensors errors, including offsets of zero signals, errors of scale factors and cross-links connections, are considered. The influence of various components of these errors and their linear combinations on the numeration accuracy of coordinates, velocity and orientation angles is investigated by the method of mathematical modeling of the SINS operation at one and a half hour intervals. To assess the linear properties of SINS algorithms, a quantitative measure is introduced — the value of the numeration error deviation, caused by a linear combination of input errors, relative linear combination of errors caused by separate input errors, as a percentage is expressed. Numerical estimates for typical trajectories of a maneuverable aircraft are obtained for this value. The obtained results can serve as the basis for the formation of technical requirements, used at the design and testing of aviation navigation systems and complexes. Keywords strapdown inertial navigation system, potential of the gravity field, gravitational acceleration, apparent acceleration, numeration errors, math modeling

An approach to automation of the distributed information systems development is proposed, which makes it possible to radically reduce the role of traditional development, up to the complete transfer this function to specialists in the subject area of an automated enterprise. It is proposed to achieve this through the development of a specialized multi-level language for describing subject areas, built on the ideas basis of the domain driven design, event storming and other means for describing business processes. A certain phasing in the implementation of this approach is proposed. Examples of implementation of some components are given. The necessity of the intermediate representation standardization for the subject area description is shown.
