Claim of US Patent No. 10,893,502

1. A positioning system comprising:at least one first reference device;
at least one target device;
a first server; and
at least one processing unit for communication with the first server and at least one of the at least one first reference device and the at least one target device;
wherein the at least one target device and the at least one first reference device are configured for communication therebetween via at least one first wireless signal set, the at least one first wireless signal set at least comprising a first-speed signal having a first transmission speed and a second-speed signal having a second transmission speed lower than the first-speed signal and transmitted after a delay from the transmission of the first-speed signal;
wherein the at least one processing unit is configured for:
determining at least one first distance between the at least one target device and the at least one first reference device at least based on the delay and a time difference between a receiving time of the first-speed signal and a receiving time of the second-speed signal of the at least one first wireless signal set communicated between the at least one target device and the at least one first reference device, and
sending position-related information to the first server at least based on the at least one first distance.
