Abstract: Apparatus and methods determine the rotational position of a spinning object. A satellite positioning system can be used to determine the spatial position of an object, which in turn can be used to guide the object. However, when the object is spinning, such as an artillery shell, then the rotational orientation should be known in order to properly actuate the control surfaces, such as fins, which will also be spinning.

Abstract: Apparatus and methods provide a kit for converting a conventional mortar round into a glide bomb. Mortar rounds are readily available to combat personnel and are small and light enough to be carried by relatively small unmanned aerial vehicles (UAVs) such as the RQ-7 Shadow. Advantageously, the kit provides both guidance and relatively good standoff range for the UAV such that the kit-equipped mortar round can be dropped a safe distance away from the intended target so that the UAV is not easily observed near the intended target.

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.
