摘要： A global positioning system using Bluetooth technology, including: a first Bluetooth master that receives satellite orbit information; a Bluetooth slave that communicates with the first Bluetooth master in a Bluetooth protocol; and a second Bluetooth master that transmits an inquiry code for communication with the Bluetooth slave in the Bluetooth protocol. The second Bluetooth master provides positioning information by requesting the satellite orbit information from the first Bluetooth master through the Bluetooth slave and transmitting the satellite orbit information to the second Bluetooth master through the Bluetooth slave.

摘要： Provided is an on-channel repeater capable of removing feedback signals based on pilot partitioning, which can efficiently remove a feedback signal by quickly coping with even a situation in which a feedback channel changes rapidly, by reducing a filter-coefficient update interval, i.e., increasing the number of times of filter-coefficient creation, through pilot partitioning, and a method thereof. The on-channel repeater includes: a receiver for receiving a signal; a subtractor for subtracting a replica of a feedback signal from the signal received in the receiver to remove the feedback signal; a replica creator for creating a filter coefficient using pilot partitioning, creating a replica of the feedback signal using the created filter coefficient, and feeding back the created replica to the subtractor; and a transmitter for transmitting an output signal of the subtractor.

摘要： A pseudo-satellite transmitter includes a GPS unit, a transmission power control unit, and a plurality of antennas. The GPS unit generates a GPS signal of a pseudo-satellite. The transmission power control unit generates a plurality of GPS signals having different power levels based on the GPS signal generated by the GPS unit and a distance from a shadow area to the pseudo-satellite transmitter. Each antenna is configured to wirelessly transmit the GPS signals with different power levels output from the transmission power control unit to a corresponding one of a plurality of shadow areas according to the distance from the shadow area to the corresponding antenna.
