Usually, we have
been keeping track of what the "best lock frequency" is vs temperature,
and with a temperature estimate, and the Doppler estimate, the range to
sweep isn't all that big.
As the signal sweeps across the receiver's bandwidth, the oscillator in
the receiver locks to the uplink signal (and follows it).
