OK, got it: no need to lock the receiver clock to birds to get stable data (e.g. Oncore+Cs) but the clock can be locked to birds to get even better data and obtain "for free" a reference clock (TBolt). The use of a stable clock (not locked to birds) feeding the receiver can show the various errors that affect the downlink having removed the clock instabilities.
Not quite right. If you lock up the clock, you do not lock to the birds, but to GPS time or UTC as received over GPS. The observed time of the birds would be a bad solution since you can't see a particular bird continously unless you is in geosync orbit.
