%X At the turn of the 20th and 21st centuries, Global Navigation Satellite Systems (GNSSs) dominated navigation in air, sea, and land. Then, medium-range and long-range terrestrial navigation systems (TNSs) ceased to be developed. However, with the development of GNSS jamming and spoofing techniques, the TNSs are being re-developed, such as the Enhanced Loran. The Polish Ministry of Defense plans to develop and implement a medium-range backup navigation system for the Polish Navy which will operate in the Baltic coastal zone. This plan is a part of the global trend. This paper presents the concept of a reserve TNS (RNS) that is based on the signal Doppler frequency (SDF) location method. In 2016, the concept of the RNS, which is based on stationary radio beacons located on coastal lighthouses, has been presented. From the military viewpoint, the use of the mobile radio beacons, which may change their location, is more justified. Therefore, the paper presents an idea of using the mobile beacons for this purpose. In this paper, effectiveness of the mobile RNS is shown based on simulation studies.
