We created a high precision Radio Direction Beacon and Radio Direction Finder that is light weight and cost effective. Our radio positioning system provides location to client devices or actively/passively detect coordinates of any radio transmission on any frequency. Our patented device called a Rotating Base Station (RBS) can direction find analog or digital radios. Our prototype currently supports 802.11 WiFi and soon Drone radios. It uses a highly directional fast rotating balanced parabolic reflector to transmit or receive signals 4 to 32 times further than normal antennas. We beam out WiFi SSID beacons with encoded angle data. At 1 watt FCC 5.8 GHz limit, range is 100 km with line of sight. With S band radar frequencies using 100-watt microsecond bursts, range is above 1000km. Any WiFi device receive our beacons and compute their angle to RBS. Multiple RBS facilitates triangulation. Our RBS uses a highly directional fast rotating balanced parabolic reflector to transmit or receive signals 4 to 32 times further than normal antennas. Our design greatly amplifies incoming radio signals and computes the precise angle of reception. We can passively detect the location of drones that continuously transmit video data for First Person View (FPV) navigation. Drones with typical 500 mW transmit power can be precisely located 70 km away with line-of-sight. Our RBS can also jam enemy drones at long range while minimizing off-bore emissions to avoid producing interference. In Positioning Mode we beam out WiFi SSID beacons in a 360° sweep with encoded angle data. At the 1 watt FCC 5.8 GHz limit with 30 dBm gain our transmit range is 100 km line of sight. WiFi devices receive beacons from multiple RBS units to triangulate their own location without GPS. Using S band radar frequencies transmitting 100+ watt microsecond bursts, our signal goes beyond 1000km. Devices like smartphones, tablets, laptops, or embedded systems can receive our angular SSID beacons with no special hardware or firmware. We can passively locate WiFi or send probe frames to WiFi devices to trigger their involuntary WiFi response so we can continuously detect their location. Our RBS also operates as a super long range WiFi Access Point (AP) with the advantage of a high gain parabolic antenna but also the omnidirectional characteristics of normal WiFi APs. Our timed and aligned transmissions give us 10+ km datalink range.
