MODERN MARINE ASTRONOMY METHODS

Abstract

At present, the methods and means of nautical astronomy are the only redundant ones for global navigation satellite systems. Naval astronomy operates with methods and means for determining the position of a ship on the high seas. The intensive development of computer methods in astronavigation began with the development of modern information technologies. Modern navigation practice is based on the widespread use of the latest satellite observation systems. However, this in no way diminishes the relevance of astronomical computation methods. Astronomical methods of determining the location of objects have significant advantages. The main one is that it is the celestial bodies that are natural "sensors" of navigation information. The presence of a large number of celestial bodies allows simultaneous measurements to calculate the elements of several isostages. In the modern world, the rapid complication of navigation conditions continues, especially in areas of intensive shipping. This circumstance stimulates the development of automated navigation systems that implement the indicated methods of nautical astronomy. Astronomical methods can be automated using astronomical systems. As a result, the time is significant ly reduced and the accuracy of solving navigation problems is increased. The article provides a structural and functional diagram of an automated astronavigation system
