Why it’s important: 

• These commercial efforts are in addition to government/military efforts, of which there is little info.
• They show China’s very aggressive approach to ensuring users have PNT.  Chinese PNT users also have access to high power terrestrial eLoran signals that serve the entire nation and its waters to 1,000nm offshore, and a 20,000km fiber timing network with 294 timing stations.
