Patent ID: 7952517

Claim:
A method of transmitting satellite positioning signal received by an external antenna to an unexposed receiver having an internal receiving antenna, comprising: (a) receiving satellite positioning signal from a satellite in an external antenna; (b) transforming the satellite positioning signal into an electric signal; (c) amplifying said electric signal into an amplified electric signal; (d) transferring said amplified electric signal by an electric cable to a transmitting antenna; (e) transforming said amplified electric signal in said transmitting antenna into an electromagnetic wave; (f) emitting said electromagnetic wave; and (g) receiving said electromagnetic wave by the internal receiving antenna of the unexposed received, wherein the internal receiving antenna of the unexposed received is shielded from directly receiving satellite positioning signal from satellites, and wherein amplification in an amplifier of the external antenna is lower than signal damping between the external antenna and the transmitting antenna.
