Abstract

A system and a method for position determination by impulse radio where first position information is determined for a first impulse radio using a positioning system, second position information is determined for the first impulse radio using at least one second impulse radio, and a position is determined based upon the first position information relative to the second position information. The positioning system can be a Global Positioning System. The determined position can be communicated to an emergency system.

Claims (26)

1. A method for determining a position of an impulse radio comprising:

determining a first position information of a first impulse radio using a positioning system;

determining a second position information of the first impulse radio using at least one second impulse radio; and

determining the position of the first impulse radio based upon the first position information relative to the second position information.

2. The method of claim 1 , further comprising:

communicating the position of the first impulse radio to an emergency system.

3. The method of claim 1 , wherein the first impulse radio and the at least one second impulse radio are not time synchronized.

4. The method of claim 1 , wherein the positioning system is a Global Positioning System (GPS).

5. The method of claim 1 , wherein the step of determining the position of the first impulse radio further comprises:

determining a time domain equivalent of carrier phase.

6. The method of claim 1 , where the step of determining the position of the first impulse radio further comprises:

resolving subcycle time differences.

7. The method of claim 1 , wherein the first position information comprises modulation cycle information.

8. The method of claim 1 , wherein the second position information comprises a time domain equivalent information of carrier phase.

9. A system for determining a position of an impulse radio, the system comprising:

a positioning receiver that determines a first position information of a first impulse radio;

at least one second impulse radio that determines a second position information of the first impulse radio; and

a processor that determines the position of the first impulse radio based upon the first position information relative to the second position information.

10. The system of claim 9 , wherein the position of the first impulse radio is communicated to an emergency system.

11. The system of claim 9 , wherein the first impulse radio and the at least one second impulse radio are not time synchronized.

12. The system of claim 9 , wherein the resolution of the first position information relative to the second position information requires determining a time domain equivalent of carrier phase.

13. The system of claim 9 , wherein the resolution of the first position information relative to the second position information requires determining subcycle time differences.

14. The system of claim 9 , wherein the first position information comprises modulation cycle information.

15. The system of claim 9 , wherein the second position information comprises a time domain equivalent information of carrier phase.

16. The system of claim 9 , wherein the positioning system is a Global Positioning System (GPS).

17. The system of claim 9 , wherein the positioning receiver is a Global Positioning System (GPS) receiver.
