Abstract: Mohammad Khalil, Hoblyk Viktor Vasyliovych (Head). Investigation of the Construction Principles and Techniques for X-ray Pulsar-Based GPS Systems with Highly Stable Parameters. Master’s thesis. - National University «Lviv Polytechnic». Lviv 2021. Extended annotation. This master’s thesis presents the results of the study of the principles and methods of construction of navigation systems (GPS) [1] with highly stable parameters based on the radiation of pulsars and quasars [2]. Alternative sources and properties of electromagnetic radiation of quasars and pulsars for navigation needs in the problems of space exploration and monitoring of the problem of loss of their functional properties by terrestrial navigation systems in cases of failure of artificial satellites of the Earth and the impact on operating systems of existing navigators on planet Earth and in outer space [3] To develop promising navigation technologies of the new generation, it is proposed to use existing radio telescopes [4], which provide electromagnetic radiation of pulsars and quasars of decimeter and centimeter wave ranges without losing their energy when passing through the Earth’s atmosphere and provide navigational receivers. In the computer mathematics environment MATLAB [5] simulation of the radiation pattern of the radio telescope RT-64 (TNA-150) to estimate the gain of the radio telescope electromagnetic waves of quasars and pulsars in the meter range, and to create promising ground navigation systems of the new generation. The object of research is promising navigation technologies based on pulsar and quasar radiation. The subject of the research is the peculiarities of construction of perspective navigation technologies on the Earth and space on the basis of radiation of electromagnetic waves of pulsars and quasars. The purpose of the study: to study the fundamental possibility of building promising ground technologies in case of failure of artificial satellites of the Earth, which provide navigational signals to the operability of existing GPS systems [1]. The main result of the work is the substantiation of the principles of construction of perspective navigation systems of the new generation on the basis of radiation of pulsars and quasars [2]. Promising navigation technologies integrate in their development the whole arsenal of existing technical developments of antennas and navigation systems. Key words: pulsar, quasar, radio telescope, GPS - systems, perspective navigation technologies, artificial satellites of the Earth, Earth ’s atmosphere, electromagnetic radiation. References: 1.
