This paper covers aircraft navigation with emphasis upon self-contained systems, although a survey of the scene cannot avoid reference to external aids. It traces briefly the evolution of self-contained systems since World War II to the present time and then attempts to forecast the way development appears likely to go in the future. The paper deals with both military and civil aviation because, in spite of the increasing importance of the latter, military navigation, as ever, leads the way to improvements for the future.

The industry of civil aviation is developing in a fast manner to occupy the increasing needs for a fast, safe and comfortable transportation. To achieve these needs, some effective programs, plans, and systems designs are required. The current reliable aircraft navigation and landing systems have relatively a low level of accuracy especially in aircraft landing stage. The best landing category could be achieved requires a runway visual range up to 50 meters and automatic landing system is not in operation yet all over the world. Aircraft navigates using Radar, Radio and Satellite navigation systems. The Federal Aviation Administration (FAA) plans to replace legacy navigation systems with satellite based navigation technology. Currently, the Global Positioning System (GPS) and its augmentations is the main satellite navigation system used all over the world for air navigation applications. The development of aircraft navigation has been performed with the enhancement of GPS augmentation systems. In this paper, aircraft navigation systems and techniques will be presented in this paper to evaluate the integrity and reliability of each system, and to make a comparison among these systems according to accuracy, integrity and availability.

Проведен краткий анализ как отечественных, так и зарубежных систем межсамолетной навигации. В ходе анализа были отражены недостатки систем межсамолетной навигации и представлен актуальный подход повышения точности системы навигации за счет применения системы технического зрения. Для определения местоположения ведущего самолета предлагается рассмотреть в качестве измерительного комплекса систему технического зрения, которая способна решать большой круг задач на различных этапах, в частности, и полет строем. Систему технического зрения предлагается установить на ведомом самолете с целью измерения всех параметров, необходимых для формирования автоматического управления полетом летательного аппарата. Обработка изображений ведущего самолета выполняется с целью определения координат трех идентичных точек на фоточувствительных матрицах. Причем в качестве этих точек выбираются оптически контрастные элементы конструкции летательного аппарата, например окончания крыла, хвостового оперения и т.д. Для упрощения процедуры обработки изображений возможно использование полупроводниковых источников света в инфракрасном диапазоне (например, с длиной волны λ = 1,54 мкм), что позволяет работать даже в сложных метеоусловиях. Такой подход может быть использован при автоматизации полета строем более чем двух летательных аппаратов, при этом необходимо только оборудовать системой технического зрения все ведомые самолеты группы The article provides a brief analysis of both domestic and foreign inter-aircraft navigation systems. In the course of the analysis, we found the shortcomings of inter-aircraft navigation systems and presented an up-to-date approach to improving the accuracy of the navigation system through the use of a technical vision system. To determine the location of the leading aircraft, we proposed to consider a technical vision system as a measuring complex, which is able to solve a large range of tasks at various stages, in particular, flight in formation. We proposed to install the technical vision system on the slave aircraft in order to measure all the parameters necessary for the formation of automatic flight control of the aircraft. We performed an image processing of the leading aircraft to determine the coordinates of three identical points on photosensitive matrices. Moreover, we selected optically contrasting elements of the aircraft structure as these points, for example, the end of the wing, tail, etc. To simplify the image processing procedure, it is possible to use semiconductor light sources in the infrared range (for example, with a wavelength of λ = 1.54 microns), which allows us to work even in difficult weather conditions. This approach can be used when automating a flight in formation of more than two aircraft, while it is only necessary to equip all the guided aircraft of the group with a technical vision system

Navigation has a huge application in aviation and aircraft automatic approach. Two widely used navigation systems are Global position System (GPS) and Inertial Navigation System (INS). Triangulation method used to determine the aircrafts location by GPS, speed whereas an INS, with the aid of gyroscope and accelerometer, estimates the location, velocity and alignment of an aircraft. Aircraft navigation is a complex task and using only one of the above navigation systems results in inaccurate and insufficient data. GPS stops working when satellite signal is not received, susceptible to interfere occasionally has high noise content, and has a low bandwidth, INS system requires external information for initialization has long-term drift errors. Certain errors like ionosphere interference, clock error, orbital error, position error, etc. might arise and disrupt the navigation process. In order to outrun the limitations of the above two systems and counter the errors, both INS and GPS can be integrated and used to attain more smooth, accurate and faster aircraft attitude estimates, as they have complementary strengths and limitations. GPS is stable for a long period and can act as an independent navigation system whereas INS is not susceptible to interference and signal losses has high radio bandwidth and works well for short intervals of time. In order to get accurate and precise attitude estimation, calculation of the parameters at different altitude using both systems is done; furthermore the comparison and contrast between the results is performed, measured quantities are transformed between various frames like longitudinal to rolling, calculation and elimination of errors is done producing the final solution. Because of integrated GPS and INS, the navigation system exhibits robustness, higher bandwidth, better noise characteristics, and long-term stability.

The paper analyses the development prospects for aircraft navigation systems using onboard geophysical field measurements. Prospective systems that are not widely applied yet are considered: magnetic gradiometers measuring the stationary magnetic field gradient, gravity gradiometers measuring the gravity field gradient, and electromagnetic systems measuring the alternating part of magnetic field. We discuss the main problems to be solved during airborne measurements of these parameters and give an overview of algorithms and hardware solutions. We analyse the results of onboard measurements and estimate the possible navigation accuracy.

In this chapter, the author presents stochastic methods in aviation. The stochastic methods are presented as methods of decision making (DM) of operators of air navigation systems (ANS) in risk and uncertainly. The ANS is presented as a socio-technical system (STS). Analysis influences the factors of professional and non-professional activities on DM of STS's operators. The author made an analysis of the International Civil Aviation Organization (ICAO) documents on risk assessment. To determine the quantitative characteristics of risk levels, models for DM by the operator of the aviation system under risk and uncertainty have been developed. The author demonstrates some interesting advantages offered by the new methodology of DM in STS and forecasting the behavior of the operator in an emergency situation (ES) for using models of DM in risk and uncertainty.

Integrated avionics architectures offer advantages such as higher flexibility, reliability, simplicity, future upgradeability and weight saving over previous federated designs. Successful implementations of integrated modular avionics (IMA) are onboard Boeing B777, B787, Airbus A380 and A350. These applications often result in development and maintenance cost not suitable for regional and general aviation aircraft. One popular approach to overcome this problem is by using integrated flight deck (IFD) supplied by avionics manufacturers such as Garmin or Honeywell. These manufacturers often optimize IFDs for applications in developed countries. For example, with the development and widespread use of satellite-based global positioning system (GPS) in the US, Canada and Europe, some terrestrial navigation equipment (e.g. ADF and DME) are no longer included in the standard IFD packages offered for commercial aviation. However, many areas in the rest of the world still use and rely largely on the availability of the ADF, DME, etc. Aircraft flying in these areas need to comply with the local requirements for terrestrial navigation systems already deployed. In this paper a study on the implementation of additional avionics equipment on Garmin G1000 for advanced regional turboprop aircraft is presented. G1000 is an integrated avionics system that integrates many electronic components including navigation, communication, course, attitude, display, etc. It has been widely used in all kinds of civil aviation aircraft. In order to conform to local and modern requirements, ADF receiver, DME transceiver, traffic alerting system and weather radar need to be integrated. Preliminary reliability analysis using fault tree method is performed for the designs to ascertain their safety as set out in the requirements for advanced regional turboprop aircraft.
