“…It will also solve the problem with the low availability of satellites, increasing the number of visible satellites for the user. In works [8][9][10] we stated that traditionally the second frequency of the dual-frequency receiver is used to increase the accuracy of positioning by mitigating the influence of the ionosphere and other atmospheric effects on the signal. The presence of the useful signal at both frequencies is usually taken for granted, and it is indeed true for the Earth service zone, as the satellite antennas were primarily designed to ensure stable and reliable navigation in this zone.…”

Satellite technologies of communication, navigation and surveillance play an important role in modern transport, and particularly in aviation. High effectiveness of global air navigation system is provided by applying data broadcasted from great numbers of satellites, located on Earth orbits. The totality of existing satellite navigation system forms global radio navigation field which parameters should be constantly monitored and controlled for providing safety requirements. The aim of this article is to share experience of creating a laboratory of satellite technologies at the National Aviation University that performs simultaneously educational and scientific tasks.

“…The requirement for reliable communication is caused by errors in navigation, guidance and control systems that are introduced at each stage. Navigation systems introduce errors in the determination of the current coordinates and orientation parameters [9], and the guidance and control system may have corresponding de ciencies when a single drone is set to the required position [10].…”

The use of stratospheric drones for data transmission requires reliable two-way communication. In this regard, it is necessary to explore the possibilities of combining existing air and ground networks for effective interaction with stratospheric drones during heavy data tra c. This article focuses on calculating the packet loss and the impact of tra c parameters on communication with drones. For the rst time, tra c characteristics of the complex network "Base Station -Stratospheric Drone -RPAS -Ground Cellular Network" are obtained. The original models are created based on MATLAB Simulink and NetCracker software. Packet loss dependences on the transaction size for different numbers of cellular users are estimated using NetCracker software. Average load dependences on the size of the transaction are obtained. Channels with different throughput are considered and the in uence of channel loading on the bit error rate is studied. Data transmission is simulated using MATLAB Simulink depending on the signal-to-noise ratio, nonlinearity levels of the base station ampli er, types of signal modulation and diameters of base station antennas. Data obtained make it possible to predict the operation of stratospheric drones. increase the coverage, capacity, reliability and energy e ciency of wireless networks. Drones can act as ying mobile terminals within a cellular network. These drones, connected to a cellular network, can use several applications, ranging from live video streaming to delivering goods. The article [17] provides detailed guidance on the UAVs use in wireless communications: 3D deployment, performance analysis, channel modeling and energy e ciency. Analytical foundations and mathematical tools such as optimization theory, machine learning, stochastic geometry, transport theory and game theory are described. The basic recommendations for the analysis, optimization and design of wireless communication systems based on UAVs are presented.
