The following describes a drone guidance system and method utilizing a plurality of Bluetooth emitters that transmit indicator information to the drone, which can utilize the indicator information to determine if it is on the intended path or alternatively determine if it is near a prohibited flying zone. In alternative embodiments, the drone can communicate with the emitters, which can relay information to a pre-flight database.
DESIGN METHOD OF BEACON-BASED POSITIONING SYSTEM
Disclosed is a beacon-based positioning system. A beacon position in which a beacon is installable is defined in a target space, and a path loss model of radio frequency (RF) signals between all beacon positions and all observation positions of a scanner is determined. Among all possible installation plans for the beacon positions, an installation plan in which different beacon signals, whose RSSIs calculated using the path loss model have significant values, are received in a number greater than or equal to a minimum reference number and a total number of the beacons installed is minimum is determined as an optimal installation plan. The optimization problem of determining the optimal installation plan may be expressed by binary linear programming.
