It seems appropriate first to define and explain the term Area Navigation that lately has almost become a slogan in discussions on short-range radio navigation aids. The term itself does not convey much because virtually any radio navigation system permits navigation in the area of coverage of the associated ground stations; for a systematic classification of navigation systems, the term Area Navigation (herein called ANAV) is unsatisfactory. It can be understood only in the context of air traffic control requirements. For a long while the requirements of short-range navigation systems were almost exclusively governed by the needs of air traffic control systems based on an airways concept. When during recent years A.T.C. methods became less associated with a fixed route structure, especially in the terminal area, the requirements to be met by a navigation system changed accordingly. There now appears to be a general trend for area navigation capability to become available as a substitute for a point-to-point navigation system.

Accuracy is an important factor in air traffic management which is why high requirements are necessary for each navigation system. The aim of this article is to describe the principles of the RelNav system and telemetry and their accuracy. We present the algorithms of the relative navigation system, which could be used for air traffic control in the case of the unavailability of satellite navigation system signals. This article sums up the different positioning methods, and deals with the accuracy of the relative navigation system (RelNav). Furthermore, the article considers the factors that influence the positioning accuracy. For this task, a computer simulation was created to evaluate the accuracy of the telemetric method. Next, we discuss the principles of telemetry and algorithms for calculating the position of the flying object (FO).

Summary of a paper presented by Dr. Bowen, as President of the Australian Institute of Navigation, to a meeting of the Institute held on 15 June 1951.Accounts of the work described in this paper have been separately published, many of them in this Journal. The paper, therefore, restricts itself to giving a summary of this work, referring the reader to the appropriate literature for further study, and to pointing to some of the outstanding landmarks over the last few years.The work referred to has been carried out by the Radiophysics Division of the Commonwealth Scientific and Industrial Research Organization in Australia and falls conveniently into two main headings, dealing with short-range aids to navigation and with air traffic control. It has been conducted for air navigation, but one at least of the navigation aids developed may find a useful application for maritime use.

Ensuring transport connectivity of the territories of the Arctic zone is largely provided by means of regional aviation. To ensure flight safety, it is necessary to equip small airfields with radar facilities, while it is not economically effective to use the traditional range of navigation radar facilities for airfields with a low frequency of use. Therefore, it is necessary to search for and justify new scientific and technical solutions to ensure the creation of navigation tools that solve the tasks facing the dispatching services of regional airfields in the Arctic zone. This article presents an analysis of global trends in the development of air traffic control systems and options for equipping information sensors for dispatching services for airfields in the Arctic zone. The appearance of equipment complexes for information support of regional airports and small aircraft airfields based on a highly informative multifunctional three-coordinate all-round radar is proposed. The application of the obtained results and the proposed technical solutions and principles for the construction of navigation aids for regional airports and small aircraft airfields will significantly reduce the cost of production and operation of a new generation of modular high-information radars and increase the safety of navigation systems.

Granas (Global RAdio NAvigation System) is a satellite-based radio navigation system with global coverage, high accuracy and continuous availability for civil users on land, sea and air. Its performance, thus, is superior to existing ground-based radio navigation systems as Omega, Loran, Decca, and so on.The principle of Granas user-position determination is similar to that of Navstar GPS or Navsat in that a user makes pseudo-range measurements to a number of satellites visible above a 5° elevation angle. These ranging operations are performed using time-of-arrival (TOA) measurements of navigation signals transmitted by satellites. Knowing the discrete positions of four or more satellites and their pseudo-ranges, a user may compute its own clock bias and its position in three dimensions (longitude, latitude and altitude).
