Abstract

A device for transmitting a satellite positioning signal received by an external antenna to an unexposed receiver having an internal receiving antenna. 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 waive 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.

Claims

1. 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 waive 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.

2. The method of claim 1, wherein said external antenna and said unexposed receiver are disposed in a mechanical vehicle.

3. The method of claim 1, wherein said transmitting antenna is connected by an electric cable to said external antenna, and said transmitting antenna is located in close proximity to the internal receiving antenna of the unexposed receiver.

4. The method of claim 1, wherein amplification in an amplifier of the external antenna is lower than signal damping between the external antenna and the transmitting antenna.

5. The method of claim 1, wherein amplification of signal received by the external antenna is higher than signal damping between the transmitting antenna and the internal receiving antenna.
