Background
Phase tracking receivers were used in applications where very
feeble received signals were needed to be received. One example is
the case of a deep space satellite where the telemetry signals can
be received here on Earth. Nems-Clark (catalog.pdf) telemetry receivers comes to
mind. Another example is the case of a precision timing receiver that
is tracking either the Mark or Space signal of a narrow shift encrypted military
VLF RTTY station or WWVB on 60 kHz or WWVL (when it was on 20 kHz) maybe
they also used to track the Omega navigation signals when they were on the
air
