For (e.g.) eLoran, each chain is independent of every other chain. So the network chain(s) run in the EU are not dependent on the chains in US/CA, are not dependent on the chains in Russia, or the Middle East: * https://en.wikipedia.org/wiki/File:NGA-Atlantic_Loran.png https://en.wikipedia.org/wiki/File:NGA-Atlantic_Loran.png The chains run by Japan are not dependent on the chains run by South Korea, would not be dependent on chains run by AU or NZ: * https://en.wikipedia.org/wiki/File:NGA-Pacific_Loran.png https://en.wikipedia.org/wiki/File:NGA-Pacific_Loran.png * https://en.wikipedia.org/wiki/Loran-C#Limitations https://en.wikipedia.org/wiki/Loran-C#Limitations India, China, and Pakistan could all run their own infrastructure: * https://commons.wikimedia.org/wiki/File:Loranstationscrkl.jpg https://commons.wikimedia.org/wiki/File:Loranstationscrkl.jp... The only agreement being the technical standards (frequencies) and timing offset for near-by chains. (And I'm Canadian.)
