Abstract
Successful economic development of the Arctic region is impossible without creating a continuous information field that covers its entire territory and is accessible not only on stationary objects, but primarily on moving vehicles — ships, cars, airplanes, etc. This information field should consist of the transmission of audio information (broadcasting programs), data (weather maps, ice conditions, etc.), navigation signals, warnings and emergency information. To ensure reliable operation in harsh climatic conditions, it must be redundant, using various means of content delivery — from satellite to terrestrial radio networks. It is advisable to use single-frequency digital broadcasting networks of the Digital Radio Mondiale standard in the low-frequency range as a backup system (and in the coming years, the main one). It is shown that digital broadcasting networks of the DRM standard are the most economical systems for covering remote areas with high reliability. To use these systems, there is all the necessary regulatory frameworks and standard high-efficiency radio transmitters. The possibility of using standard antenna systems is shown. An example of frequency-territorial planning and a program of preliminary field tests in the experimental zone have been developed. The international cooperation of the states belonging to the Arctic region will significantly reduce the costs of conducting research necessary before the introduction of the implementation by using the existing broadcast infrastructure. It is shown that the entire Arctic region of the Russian Federation, including the Northern Sea Route, can be covered by a total of 6 transmitters with three frequencies, a total power consumption of only 450 kW.
Keywords:digital radio broadcasting, DRM, LF range, single frequency network, antenna, broadcast transmitter.
