Abstract:
1. A driving method of a global positioning system having: a first Bluetooth master to receive satellite orbit information; a Bluetooth slave to communicate with the first Bluetooth master in a Bluetooth protocol; and a second Bluetooth master to transmit an inquiry code for communication with the Bluetooth slave in the Bluetooth protocol, the method comprising: establishing a connection via the Bluetooth protocol between the first Bluetooth master and the Bluetooth slave; transmitting, by the second Bluetooth master, the inquiry code to the Bluetooth slave to determine if the Bluetooth slave is capable of receiving the satellite orbit information from the first Bluetooth master; requesting, by the second Bluetooth master, the satellite orbit information from the first Bluetooth master through the Bluetooth slave; requesting, by the Bluetooth slave, the satellite orbit information from the first Bluetooth master in response to the requesting of the satellite orbit information by the second Bluetooth master; transmitting the satellite orbit information requested by the Bluetooth slave to the Bluetooth slave from the first Bluetooth master; transmitting, from the Bluetooth slave, a frequency hop selection (FHS) packet to the second Bluetooth master to establish a set frequency for a connection via the Bluetooth protocol between the Bluetooth slave and the second Bluetooth master; and transmitting the satellite orbit information from the Bluetooth slave to the second Bluetooth master in response to the establishment of the set frequency so as to transmit the satellite orbit information from the first Bluetooth master to the second Bluetooth master through the Bluetooth slave.
