Synthesis of the topology of the integrated navigation and communication system functioning in the conditions of influence

The paper considers the integrated use of satellite radio navigation systems and reference stations on aircraft, which makes it possible to improve the accuracy of determining the location of mobile objects. When constructing the topology of local radio navigation systems, the position of reference stations was determined, taking into account the probability of minimal interference on them, varying the protective resource of the positioning subsystem (energy, frequency, signal and spatial) while meeting the remaining requirements.
