1. A hybrid GPS translator adapted to relay a semi-processed, reduced-bandwidth GPS signal, the hybrid GPS translator comprising:

  • a frequency-locked loop (FLL) configured to provide a frequency measurement associated with baseband I and Q signals, wherein the baseband I and Q signals are downconverted from a GPS carrier signal, the FLL being configured to provide a first signal indicating a frequency error between the baseband I and Q signals and a second signal whose frequency corresponds to the frequency measurement; and

    an interface circuit coupled to the FLL to receive the frequency error and the frequency measurement, wherein the interface circuit is adapted to couple to a downlink circuit that can transmit the frequency error and the frequency measurement to a remote location.
