Planning a route for a vessel’s passage from a port of departure to a port of destination is a topical, complicated and multifaceted problem. Due to the constant weather and ice condition changes along the vessel’s course the problem of planning an optimum route should be solved dynamically taking into consideration a current and predicted situation. Thus, using the information provided by the meteorological services according to satellite monitoring data is considered promising. Nowadays there is a great number of controlled means of sensing which allows us to obtain the information on both atmosphere and hydrosphere conditions of the Earth practically in real time. At present an orbital grouping of the Earth remote sensing satellites for measuring surface wind speed over the ocean, ice conditions and significant wave height has over ten space vehicles, and their number is constantly increasing. Within the framework of e-navigation development, using the meteorological data directly on shipboard has become possible. The problem of modeling the satellite monitoring to evaluate the frequency of updating the data on weather in the selected position of the earth’s surface, which are provided by existing meteorological services, is considered in the paper. The wellknown equation of artificial satellite motion in an elliptical orbit is the basis of this model. The obtained results contribute to formulate a systematized concept that the use of meteorological satellite data to solve the problem of planning long range navigation in view of weather and ice conditions is promising. In case there are data from only one satellite, even with the widest swath (e.g. QuikScat), the mean time of data obtainment (the data age) at the Arctic latitudes will be from some hours up to twelve hours. The Average Wait Time of the sensing data for both an individual meteorological satellite and a group of meteorological satellites has been analyzed in the paper. The graphs of the time intervals distribution between consecutive observations of positions on the Earth surface by the different groups of meteorological satellites at the Arctic latitudes are presented. The conclusion on the implementability of planning the vessel route, taking into account the ice conditions when there is a surface wind and sea along the intended vessel course, in view of the information obtained from existing satellite weather sensors is made.
