title: MAIN PRINCIPLES OF THE SATELLITE SYSTEM PROVIDING PNT INFORMATION FOR MOVING OBJECTS UNDER GNSS VULNERABILITY
abstract: Background. GNSS systems are the main source of PNT information (positioning; navigation; timing) for different systems that can be applied in industries, scientific research and defense. GNSS signal outages, whether natural or as intentional influence (jamming; spoofing), become an increasing problem and are the reason for research aimed at using alternative GNSS sources of PNT information, especially for moving objects.Objective. General design synthesis of the system providing PNT information
