The first global positioning system satellite is operable to generate a first position signal. The second global positioning system satellite is operable to generate a second position signal. The broadcast transmitter is disposed in a first location and is operable to transmit a broadcast signal having broadcast transmitter identification information therein. The database has correlation data therein, and is operable to generate a first correlation, a second correlation and a correlation signal. The first correlation is based the broadcast transmitter identification information and the first location. The second correlation is based on the first location and one of the first global positioning system satellite and the second global positioning satellite. The correlation signal is based on the second correlation. The communication device includes a first receiver, a processing portion, a transmission portion, a second receiver portion and a communication portion. The first receiver portion is operable to receive the broadcast signal. The processing portion is operable to extract the broadcast transmitter identification information from the broadcast signal. The transmission portion is operable to transmit the broadcast transmitter identification information to the database. The second receiver portion is operable to receive the correlation signal. The communication portion is operable to transmit a communication signal to the one of the first global positioning system satellite and the second global positioning satellite, based on the correlation signal. ## Claims ### Claim 1 A communication device for use in a system including a first global positioning system satellite, a second global positioning satellite, a broadcast transmitter and a database, the first global positioning system satellite being operable to generate a first position signal, the second global positioning system satellite being operable to generate a second position signal, the broadcast transmitter being disposed in a first location and being operable to transmit a broadcast signal having broadcast transmitter identification information therein, the database having correlation data therein, the data base being operable to generate a first correlation, to generate a second correlation and to generate a correlation signal, the first correlation being based the broadcast transmitter identification information and the first location, the second correlation being based on the first location and one of the first global positioning system satellite and the second global positioning satellite, the correlation signal being based on the second correlation, said communication device comprising: a first receiver portion operable to receive the broadcast signal;
