A system for tracking high-dynamic targets by relaying semi-processed GPS
signals to a remote signal processing station with a relatively small and
efficient bandwidth is described. Such processed GPS signals can be
provided in a high-dynamic environment without the assistance of an
inertial measurement unit (IMU). One embodiment includes a hybrid
translator that is a hybrid between a full GPS navigation system and a
translator system. The modulated GPS signals, such as modulated C/A
codes, are pre-processed to reduce the amount of information required to
reconstruct the GPS signal received by the hybrid translator. For
example, the GPS signals can be processed to a pseudo-range measurement
and an indication of an amount of corruption of delta range in the
pseudo-range measurement, which are then provided to signal processing at
a remote location, such as at a ground station, via a wireless downlink.
