Simulation Modeling of Strapdown Inertial Navigation Systems Functioning as a Means to Ensure Cybersecurity of Unmanned Aerial Vehicles Navigation Systems for Dynamic Objects in Various Correction Modes*

In this paper the problem of simulation of strapdown inertial navigation systems functioning as an option to strengthen UAV resilience against attacks on the objects’ positioning subsystems is considered. Although strapdown inertial navigation system is the basis of the UAV navigation, its readings need to be corrected. Readings of the Global Navigation Satellite System is the main means of correction, but its signals may be unavailable if a cyberattack occurs. This work considers a multi-factor strapdown inertial navigation system correction model, including through Global Navigation Satellite System and other means of correction, and this model is more resistant to cyberattacks. Qualitative assessments of imitation modelling results are presented in order to analyze the properties of developed algorithms of integrated processing of information from strapdown inertial navigation systems.
