providing a position determining device;

coupling the position determining device with the portion of the electrical power transmission line located intermediate the plurality of supports coupled with the electrical power transmission line; and

determining the position of the coupled position determining device to determine the position of the portion of the electrical power transmission line.

2. The method according to claim 1 wherein the determining comprises determining using another position determining device configured to determine the position of the coupled position determining device relative to the position of the another position determining device.

3. The method according to claim 2 wherein the determining comprises determining using the position determining devices comprising at least one of an optical distance measuring device and a target.

4. The method according to claim 2 wherein the determining comprises determining using the position determining devices comprising at least one of a laser and a reflector.

5. The method according to claim 2 wherein the determining comprises:

determining the distance intermediate the position determining devices; and

determining a plurality of angles defined by the position determining devices.

6. The method according to claim 5 wherein the plurality of angles include a verticle angle and a horizontal angle.

7. The method according to claim 1 wherein the determining comprises determining sag of the portion of the electrical power transmission line.

8. The method according to claim 1 wherein the determining comprises determining swing of the portion of the electrical power transmission line.

9. The method according to claim 1 further comprising:

communicating information of the position determining device after the determining; and

receiving the information within a base station.

10. A method of determining a position of a portion of an electrical power transmission line comprising:

providing a first position determining device and a second position determining device;

coupling one of the first position determining device and the second position determining device with a portion of an electrical power transmission line; and

determining the position of one of the first position determining device and the second position determining device relative to the other one of the first position determining device and the second position determining device to determine the position of the portion of the electrical power transmission line.

11. The method according to claim 10 wherein the providing comprises providing a first position determining device and a second position determining device individually comprising one of an optical distance measuring device and a target.

12. The method according to claim 10 wherein the providing comprises providing a first position determining device and a second position determining device individually comprising one of a laser and a reflector.

13. The method according to claim 10 wherein the determining comprises:

determining the distance intermediate the position determining devices; and

determining a plurality of angles defined by the position determining devices.

14. The method according to claim 13 wherein the plurality of angles include a verticle angle and a horizontal angle.
