Abstract

The purpose of this paper is creation of an efficient software and hardware model of a groundmobile object navigation system. Simulation process is one of the key instruments for engineering solutionsdevelopment at all stages of a complex technical system lifecycle. Navigation system model describedin this paper is software-hardware by nature and is implemented as software modules that supporthardware interaction with each other. The described system of ground object navigation systemsimulation has been developed in the course of several design projects and scientific research works.The developed model of a ground mobile object navigation system includes several programming units.Each of these units simulates the operation process as close as possible to the original. Internal andexternal interaction interfaces and navigation system communication protocols are also simulated withthe account for real object operation cyclograms. It should be noted that one of the main advantages ofa software simulation over a developmental testing or breadboarding is the opportunity to perform aprofound analysis of operation algorithms without the use of any additional resources. At the same time,it is often necessary to perform firmware design in order to make the simulation process identical withthe real operation. The process of navigation system architecture simulation allows performing a comparativeanalysis of several base components sets and their interaction patterns. Such comparison resultsin an optimal system structure providing the information user with navigation data in the mostefficient way. The paper determines basic simulation process tasks. The simulation stage may becomecrucial for complex systems design as it may aid achieving the best technical result. The proposed structure,key elements of a ground navigation simulation system and approaches to their interaction arrangementhave been approved in the course of several research and development works. At the sametime, it was found that the validity of developed models and their compliance to simulated units allowsperforming a highly reliable navigation system analysis. The developed software-hardware model allowedprocessing telemetry records obtained under different product operation conditions, performingtheir analysis and developing engineering solutions that increase the efficiency of navigation systems.
