21st century challenges
Opis:
For nearly the entire post-World War II period, naval and air navigation relied primarily on ground-based radionavigation systems. However, the spontaneous development of satellite systems gradually led to their disappearance. They are currently used partly in air operations and marginally in maritime navigation in some areas around Asia, in Russia and in the Middle East. However, at the beginning of the 21st century, the threat of effective interference with satellite systems began to be raised, which led to an increased interest in restoring or upgrading ground-based systems as backup systems in the Western world. In this context, the approach of Russia is interesting, as it is associated with the vast majority of deliberate GPS interference. There are reports in the world literature that various ground-based radionavigation systems operating in Russia are still observed. The article analyses, on the basis of the few available sources, information on the ALFA system, about which the least is known, and there are many indications that it is ready for use.

Opis:
Vessels engaged in coastal navigation must have their position determined with high accuracy. This can be ensured only by satellite systems such as GPS and GLONASS. The paper presents generalized concepts of geometrical factors of a navigational system. Such factors are used in the analysis of the accuracy of various radionavigational systems aimed at selecting the best system for a given area. The modern process of navigation is described in a four-dimensional space - three geometric dimensions and time. For this reason both the description and analysis of navigational systems should be performed in the same space. The traditional geometric factor of the land-based radionavigational system was generalised to include the factors GDOP, PDOP, HDOP, VDOP and TDOP for the needs of the accuracy analysis of a GPS system. These terms are related to the so-called geometry of navigational system - through mutually related positions of gradients of navigational functions determining position Iines (hyperplanes). They are connected with non-Iinear regression through a probabilistic relation between the measured navigational parameters. Consequently, the concept of geometric factors in the process of navigational parameters estimation can be also extended to include a larger number of dimensions appropriate for the state vector.
