19--23

Since many years the most frequently method used for position fix in transport are global satellite navigation systems (SNS) as GPS and GLONASS and Satellite Based Augmentation System as EGNOS, GAGAN, MSAS and WAAS. Next global SNS (Galileo and BeiDou) and SBAS (SDCM) and KAAS) are under construction. The generic name given to all these mentioned above systems is Global Navigation Satellite System (GNSS). Since 2010 GNSS Market Report, edited by the European GNSS Agency (GSA), takes a comprehensive look at the global GNSS market providing detailed analysis per market segment (currently 9 segments) and application type (currently depending on segment 4, 8, 11 or 13). In order to show the different distributions of these two parameters in different continents the world was divided into six regions (European Union, Russia and Europe without European Union, North America, Asia‒Pacific, Middle East and Africa, South America and Caribbean). The distributions of installed base of GNSS device and total revenue of GNSS devices sales by region and application in selected years for all four modes of transport (area, maritime, rail and road) are presented. In these analysis new and emerging GNSS trends by all these modes and the population numbers in each region was taken into account also.

This research analyses the competitive advantages of road and rail transport through the example of Ukraine transportation market. Spheres of efficient usage of rail and road transport while transporting perishable goods have been studied. The key factors influencing the mode choice, as well as the kinds of cargo that depend on the mode choice have been determined with the help of revealed preference data. A mathematical model of mode choice has been offered. The criterion of the effectiveness of this model is the economical profit of the logistics system ‘shipper – carrier – receiver’. The advantage of using the suggested model is the possibility of calculating invisible costs while evaluating alternative transport mode, including funds immobilization and cargo loss. The tools in the study are the methods of system analysis, mathematical modelling, regression analysis and expert evaluations. The acquired results can be used while justifying the mode choice and determining the spheres of efficient usage of various modes of transport. It has been determined that the factor for using the rail is the distance longer than 600 km, as the economical profit of the logistics system is higher in this case. At the same time, with distances shorter than 600 km, road transportation is a better choice.
