  • Patent number: 7183971
    Abstract: 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.
