The article examines the problems of navigation and communication with the use of satellite technologies in road transport in the context of the growth of globalization processes in the world economy and the transformations of freight transport technologies caused by a large-scale transition to transport with zero emissions and the development of unmanned vehicles. The paper discusses the principles of building a global high-speed broadband satellite Internet with low latency. Potential capabilities of technologies such as digital antenna arrays and laser communication channels used in such systems are analyzed. Also considered are the existing and potential problems, both technical with electromagnetic compatibility with existing satellite communication systems and between systems under construction or planning, and legal caused by changes in the principles of information transfer at the interstate level. The main players in the emerging market of high-speed satellite communications are considered and the parameters of the systems declared by them are described. The comparison of the current state of building satellite constellations of individual projects is carried out and the ability to implement the announced plans by individual companies is analyzed. The disadvantages that create obstacles for the introduction of high-speed satellite communications in road transport at the moment and the directions of their overcoming are highlighted. Considering the potential of satellite Internet systems, the current state of construction, as well as existing technical and legal restrictions, the introduction of reliable satellite communications will significantly speed up the transition to autonomous unmanned vehicles. In this regard, the most successful opportunities for the new communication technology will be able to realize the transport companies, which will simultaneously update the fleet of vehicles towards zero emissions and with unmanned technologies.
