I wonder what navigation system North Korea is using/planning to use for its ballistic missiles.

For the shipping containers (not ballistic missiles) they'll most likely smuggling these in on, for the next few years, any COTS system (on an appropriately flagged freighter) will suffice to get them across the Pacific. From there they'll just usual visual identification to get it close enough to place it could do enough damage. Like near the Embarcadero, say.
