Abstract
Dynamic development of navigation technologies opens up possibilities for the successful solution of a wide range of navigation tasks of mobile objects. For a long time the extension of the scope of navigation systems for transport applications was constrained by their high cost. The emergence of a small cheap inertial sensors, based on MEMS technology have resulted in integrated navigation systems, including the inertial and satellite GPS/GLONASS inertial modules. For solving problems of navigation of ground vehicles the integrated system is combinated with odometer. Nowadays a number of car navigation systems were made including the odometer along with the inertial measurement unit and a receiver of a satellite navigation system. However, most of these systems only exists in the form of models. The article provides the option of constructing the integrated navigation system of a vehicle brought to practical implementation. The analysis of the errors of the navigation system was made. The method of correction of errors due to the damping of the errors in speed with subsequent consideration of the damping of the amendments was proposed. Method is distinguished by ease of implementation and reliability. Correction of the navigation parameters calculated on the base of measurements of inertial sensors and odometer is permissible only when it is known that their accumulated errors have exceeded the corresponding error of the satellite navigation solution. Essentially new to the theory and practice of operation of vehicle is the introduction of a system of criteria characterizing the stability of mode generation navigation parameters. In article the numerical value of criteria-based assessments are of interest to developers of navigation systems, since accounting provides the reliability of the determination of output parameters of the system. The practical value of the presented research results, is that they can be used in the construction of high-precision navigation system of a ground vehicle.
