LORAN, short for long range navigation, is a hyperbolic radio navigation system developed in the United States during World War II. eLORAN is a fourth generation LORAN technology and incorporates a digital signal, differential correction capability and a low bandwidth one-way data channel eLORAN receivers now use all in view reception, incorporating signals from all stations in range, not solely those from a single GRI, incorporating time signals and other data from up to forty stations. These enhancements in LORAN make it adequate as a substitute for scenarios where GPS is unavailable or degraded. In recent years the United States Coast Guard has reported several episodes of. The eLoran data channel will reportedly transmit station identification, almanac, absolute time, leap-second offset, skywave warning, signal failure warning, message authentification, differential LORAN and GPS correction, and official-use messages. In addition, eLoran will apparently be accurate to approximately 50 feet. The engineers in charge of developing eLoran are making great efforts to. eLoran meets ITU requirements in G.811 for primary reference clocks 6 Table 1 - eLoran System Performance Requirements One of the data channel messages is used to provide real-time differential corrections. These corrections are provided via reference stations that detect tiny variations in the eLoran signal, similar to the differential GNSS reference stations, allowing receivers to correct.
