Cooperative Target Positioning System
20230141969 · 2023-05-11 ·

A system provides a way to determine angle of bearing to a target receiver/transmitter relative to plural beacon stations with rotating directional radiation patterns. The target is “cooperative” in that it transmits a “report” message when the target receives maximum signal strength from a beacon station. Triangulation from multiple beacon transmitter sites can be used to determine the target's position.

PERIODIC PRIORITY BASED SCAN SCHEDULE
20230417856 · 2023-12-28 ·

A device includes a controller configured to determine a first periodic priority function based on a first emitter signal periodicity of a first emitter type. The controller is also configured to determine a second periodic priority function based on a second emitter signal periodicity of a second emitter type. The controller is further configured to generate a scan schedule of a receiver system based on at least the first periodic priority function and the second periodic priority function.
