For global navigation satellite system (GNSS)-independent operation of auxiliary PNT systems, one or more ground stations of the auxiliary system have access to a non-GNSS source of precision timing. That source and known locations of the ground stations may be used to derive timing corrections to account for imperfect clocks in the satellites for non-purpose-built satellite systems being used for PNT. Crosslinks between satellites and/or propagation of timing correction through other ground stations are used to better control the timing and resulting precession of PNT in the PNT auxiliary system. The timing correction may be provided as a service to end users, other constellations, and/or other satellite operators.
