Method for active GPS receiver using by BTS position remote input

PURPOSE: A method for operating a GPS receiver by using a remote base station position inputting function is provided to input position information on a base station to a GPS receiver . CONSTITUTION: When an initial power is applied, a system checks an inner operation, and if the operation is normal, the system requests a BSM to send position information(S102-S110). If the position information is received within a set time, the system sets an operational position to the position information, and if at least more than one satellite signal is received, the system enters a normal operational state(S112-S120). If the position information is not received within another set time, the system starts calculating position information(S122-S124), and checks whether more than 4 satellite signals are received(S126). If so, the system calculates position information(S128). The system accumulates the calculated position information values, and if the accumulated time elapses at a predetermined time, the system sets an operational position to the calculated position information(S130-S132).
