The paper is devoted to the problem of optimal path planning for long-distance navigation of vessels. It is stated that the weather conditions on the route have a significant effect on the vessel’s movement. In this regard, it seems expedient to solve the optimization problem taking into account dynamically, taking into account the current and forecasted weather on the route and the technical capabilities of navigation in heavy weather. The authors propose using weather information obtained with the help of special meteorological satellites for this purpose. At the same time, an important question is the answer to the question of the characteristic age of meteorological data obtained in this way. In order to get an idea of this aspect of the work of meteorological satellites, the problem of modeling the motion of an Earth satellite in the classical representations of celestial mechanics is presented. At the same time, estimates of the age of weather data at the Earth’s surface are obtained depending on the geographical latitude of the site and the characteristics of the sensors and orbit of the satellite. An approach to the selection of meteorological satellites for collecting weather data on the planned route of the vessel is proposed. Based on the modeling results, a conclusion is made about the constructive feasibility of the idea of planning the ship’s route, taking into account the weather data by existing technical means.
