Abstract:
A comprehensive analysis of current trends in the development of inertial navigation systems for unmanned aerial vehicles has been carried out, based on an extensive patent study based on the analysis of a large number of patents covering the period from 2003 to 2024, which allows us to obtain a reliable picture of technological progress in this area. The main focus of the work is on four key areas of improvement of inertial navigation systems: improving the accuracy of determining coordinates, increasing reliability and resistance to external influences, reducing weight and cost, as well as expanding the functionality of the systems. A special place in the study is occupied by the analysis of the development of autonomy and noise immunity as priority areas of modernization. In the course of the study, a detailed analysis of the element base of foreign inertial navigation systems of tactical class was carried out, and the main technical characteristics of modern systems were identified. Based on the patent analysis, the leading developers in this field have been identified and a picture of the geographical distribution of innovative developments has been compiled. The methodological basis of the research was an integrated approach, including patent analysis, comparative evaluation of technical characteristics and identification of trends in the development of inertial navigation systems. The results of the study make it possible not only to assess the current state of technology, but also to form forecasts for the further development of autonomous navigation systems for unmanned aircraft.
