We still maintain Loran C[0]. Interesting to note receivers have been developed to grab the radio signal from all available stations, up to 40, and triangulate location with eLoran. It's a nice to have as backup to GPS however I'm not sure if it is effective against jamming or spoofing. So, the navy still teaches celestial navigation to officers. [1]
EDIT: Apparently Loran C was discontinued in 2010.

- sokoloff 7y ago> We still maintain Loran C What does "still maintain" mean in this context? My Loran-C receiver stopped working years ago when we turned off the signals. https://en.wikipedia.org/wiki/Loran-C#Loran-C_in_the_21st_century https://en.wikipedia.org/wiki/Loran-C#Loran-C_in_the_21st_ce...
- jcrawfordor 7y agoLoran-C has been discontinued. However, there are occasional ongoing proposals to restore it as "eLORAN" using newer digital transmitting and receiving equipment, to provide a terrestrial backup for GNSS. These have mostly fallen flat for simple funding reasons, but increasing attention to ASAT warfare keeps discussions going.
