Popis: The basis for ensuring the navigational safety of a ship is knowing the coordinates of its location at a given point in time. In modern conditions, the coordinates of the ship position in most cases are obtained using the global navigation satellite systems. However, there is a problem when using these systems, namely, failures in receiving navigation information from satellites. The causes of failures are interference to the radio signal of both natural origin and artificial (destructive) origin, caused by the interference of radio suppression equipment. A solution to the problem of detection of destructive interference in the radio channel of the satellite-receiver by using navigation on celestial bodies is proposed. The possibility of using navigation on celestial bodies in modern conditions implies efforts to improve this method and includes a set of measures. Among the set of measures, two directions are distinguished. The first direction is the improvement of the means for measuring the navigation parameters. The second direction is the improvement of the computing tools necessary for calculating the coordinates of the ship position, as well as solving navigational problems of ensuring navigation safety, namely, determining instrument corrections, providing time service on the ship, determining illumination and selection of luminaries for observation. The second direction of improving the navigation of the celestial bodies, namely, the identification of the trend in the development of computing means of navigation on the celestial bodies is considered in the paper. As a result of the work, the general trend of the global market which can be used to judge the growth and popularization of the maritime industry, is presented; the uneven development of the functionality of the presented programs is revealed; the advantages and disadvantages of this phenomenon are described. As confirmation of the growing relevance, reports of the international analytical organizations indicating the growth of the marine radio electronics market by 8.1 % per year until 2025 are cited.
