WYBRANE PROBLEMY KOMPENSACJI BŁĘDÓW BEZKARDANOWEGO SYSTEMU NAWIGACJI INERCJALNEJ AHRS/INS

2023-12-28T18:29:32+00:00

The paper presents algorithms for compensating selected errors of the AHRS/INS system at various stages of its construction and testing. The object of the research was a laboratory model of the system built at the Air Force Institute of Technology. Methods of identifying parameters of measurement signals and Kalman filtering are presented. Methods of compensation of instrumental errors related to the mounting geometry of measuring sensors used in the system were discussed. Problems related to the compensation of stochastic errors in the measurement circuits were also presented. One of the more difficult problems is the compensation of the BIAS error and the compensation of the non-commutativity of rotations around the measurement axes. Accurate compensation of errors in cardanless inertial navigation systems has a large impact on the accuracy of determining the attitude in AHRS systems and the accuracy of determining the position in INS systems.

THE COVID-19 PANDEMIC AND THE DEVELOPMENT OF BIOMETRIC TECHNOLOGIES AT AIRPORTS

2023-12-07T13:05:00+00:00

The global COVID-19 pandemic has brought the entire global economy to a standstill. One of the sectors that was hit hardest was undoubtedly air transport. The crisis caused by the outbreak of the pandemic was the first in the history of modern civil aviation to cause huge financial losses that will be built up for years. Since the outbreak of the pandemic, airports and airlines have been constantly trying to minimize the risk of spreading infection by introducing additional standards and procedures related to hygiene and healthcare. In order to minimize the transmission of the Covid-19 virus, airports have appreciated biometric technologies, in particular the contactless variant. Passenger path automation minimizes the risk of virus transmission and increases operational efficiency and protects passengers and staff from health hazards. Optimization of travel processes through the use of biometric methods offers greater security, as well as greater comfort and shorter waiting times. The article analyzes the possibility of using biometric technologies in airports, indicates the legitimacy of its use in the era of a pandemic and its use in the future.

THE CONCEPT OF DETERMINING GROUND SPEED WITH LIMITED ACCESS TO GNSS SIGNAL.

2024-01-03T14:35:32+00:00

This article presents an innovative approach to navigation using image recognition in situations characterized by limited access to GNSS (Global Navigation Satellite System) signals (signal interference). The presented system relies on image processing to define the characteristic edges of random objects. Subsequently, the actual speed of the moving object (UAV) is obtained based on changes in the object's position. The article aims to show the potential of image recognition in navigational systems. The actual speed obtained by the image recognition can be used to correct the inertial navigation system.

CLASSIC ANALOG PILOT INSTRUMENTS AND “GLASS COCKPIT” IN THE CONTEXT OF PILOT’S PREFERENCES AND CONFIDENCE IN THEIR USE DURING FLIGHT

2024-01-03T09:31:54+00:00

With the development of aviation, more and more improvements have been made to existing aviation technologies and applications. These efforts are aimed at optimizing every aviation operation and ensuring maximum safety during flight. Cockpit and in-flight equipment have also begun to seek out new technologies. Since the introduction of new technologies into the aviation world, pilots have been tasked with adapting to new instrument readings. This article is to present the authors' research to determine the degree of pilots' confidence and comfort in using digital glass cockpit imaging, along with an indication of respondents' subjective opinion of digital and analog imaging of pilot information. The study used a diagnostic survey on a sample of 67 respondents to show the differences in piloting and individual pilots' attitudes toward a particular way of visualizing instrument indications in the cockpit. The analysis of the data showed that the vast majority of pilots have experience in performing aircraft operations in a "glass cockpit" and overwhelmingly prefer such a display of indications or do not experience significant differences in piloting in the context of instrument display. Respondents note differences in flying with digital versus analog equipment. In addition, they indicate that they are much more likely to make mistakes resulting from misreading pilot information when using analog flight instruments. At a time when "glass cockpits" are becoming more widely used in general aviation as well, it is necessary to know the differences resulting from the different way of presenting information, but especially the preferences of the pilot crews, who are directly responsible for flight safety.

CONCLUSIONS FROM THE WAR BY THE RUSSIAN FEDERATION AGAINST UKRAINE FOR SECURITY SCIENCE

2024-01-02T13:30:58+00:00

The war waged by the Russian Federation against Ukraine triggers a number of important observations for the science of security. They have both a political, military, economic, social, technical and cultural dimension. They are all important and point to a dynamic picture of the security sciences being shaped. The purpose of this article is to indicate certain regularities from the analyzed war for security sciences. These are the new accents put by contemporary war thought. This allows us to set directions for change and define research fields within this discipline. The subject of research here are the regularities of this war, and the subject of both warring states. The time caesura is the first 14 months of this war. The main research methods include: analysis, evaluation, induction and deduction, and generalization.

STAGES OF THE TRAINING PROCESS FOR AIRCRAFT MAINTENANCE PERSONNEL

process. The basis that provides the context for undertaken training activities is to create favorable conditions for development. This issue remains key to ensuring aviation safety. The aim of this article was to analyze the stages of the aircraft maintenance personnel training process. Proper preparation and conduct of training consists of several stages, each of which is developed on the basis of information obtained as a result of the previous one. Training of SIL staff is time-consuming, primarily due to the extensive scope of topics. One of the key problems that arise after completing the training is translating new knowledge and skills into the way of performing tasks in practice. Lack of appropriate support from the superior or the organization may result in the training participant finding it difficult to modify his or her way of working and returning to old habits.
