The present work is modelling the satellite track to evaluate period of updating data from weather satellites in the selected position. The results help to formulate a concept that use of meteorological satellite data allow planning long range navigation in view of weather and ice conditions. Mean sounding data expectancy time analysis has been made for both an individual meteorological satellite and a group of meteorological satellites in this paper. Graphs of time intervals between consecutive observations of positions on the earth’s surfaces by different groups of meteorological satellites at the Arctic latitudes are presented.
Ensuring safety of navigation is a multifacitated problem, which constantly attracts researchers’ attention. Within the framework of this problem a wide circle of typical tasks, one of which is a vessel’s route planning from the port of departure to the port of destination, has been formed (Akmaykin, 2017a).
A route planning is carried out taking into account a lot of factors. The main ones are geographical characteristics of the passage area and technical capabilities of the vessel (e.g. maximum sailing range, speed, draft, length). There are some known methods of route planning connected with the solution of optimization tasks allowing for direction and speed of both wind and current along the route and minimizing the time of the passage and fuel consumption (Lin, 2013; Lu, 2015).
When planning the route of the passage in the Arctic region economic criteria are of no special importance as compared with the trajectory reading relating to safety. Polar waters are characterized with a higher complexity of navigation, first due to adverse weather conditions as well as frequent and severe storms, poor visibility, complex ice situations, risk of icing, a quick change in the weather. In conditions when there is a great number of variable factors, navigators may lack for necessary knowledge and experience to take the correct decision on the choice of a safe route. In this case automated systems for route planning are advisable to use. These systems are supposed to solve the problem dynamically taking into consideration both current and predicted situations, which data must be trustworthy. Here the use of information provided by special meteorological services according to satellite monitoring data is considered promising. Nowadays there is a great number of satellites (more than ten) fitted with aids for remote sounding of the Earth, which help to obtain information on condition of atmosphere and hydrosphere practically in real time; the number increases constantly (Ruzicka, 2017). Satellite aids can measure wind speed above the water surface and the height of waves to assess ice conditions. Within the framework of e-navigation, it has become possible to use their meteorological data directly aboard vessels (Wang, 2018).
