Satellite aided location tracking with user interface

1. A method, comprising:

receiving first user input that is specified in a first user interface, wherein said first user input enables definition of a perimeter associated with a departure location;

receiving, via a communications network, a motion position report from an asset, said motion position report being transmitted when it is determined that said asset has achieved a moving condition, said moving condition being determined based on an analysis of a first non-zero amount of time that said asset is moving as compared to a second non-zero amount of time that said asset is stationary; and

initiating a transmission of a notification message to a user that said asset has departed said departure location after receipt of said motion position report from said asset.

2. The method of claim 1 , wherein said first user input defines a circular perimeter.

3. The method of claim 1 , wherein said first user input defines a polygon shaped perimeter.

4. The method of claim 1 , wherein said first user input is received via a web interface.

5. The method of claim 1 , wherein said motion position report includes position information.

6. The method of claim 5 , wherein said position information is GPS code phase measurements.

7. The method of claim 1 , further comprising determining whether a determined position of said asset is outside of said perimeter associated with said departure location.

8. The method of claim 1 , further comprising transmitting a position history of said asset via a web interface, said position history including a departure event associated with a time of day indication included in said motion position report.

9. The method of claim 1 , wherein said moving condition is based on a determination that said first non-zero amount of time is greater than said second non-zero amount of time by a threshold amount.

10. The method of claim 1 , wherein said first non-zero amount of time and said second non-zero amount of time are measured during the same predefined time period.

11. The method of claim 1 , wherein said notification message is sent via email.

12. The method of claim 1 , wherein said notification message is sent via telephone.

13. A method, comprising:

transmitting first information that enables a user device to display a first user interface, said first user interface enabling a user to enter first user input that enables an identification of an asset; and

transmitting second information that enables a user device to display a position history of said asset, said position history including a plurality of positions of said asset, wherein a first of said plurality of positions has an associated indication that said asset has departed, wherein said associated indication that said asset has departed is based on an analysis during a predefined time period of a first non-zero amount of time that said asset is moving and a second non-zero amount of time that said asset is stationary.

14. The method of claim 13 , wherein said moving condition is based on a determination that said first non-zero amount of time is greater than said second non-zero amount of time by a threshold amount.

15. The method of claim 13 , wherein said position history is a listing of a plurality of positions from a departure location to a destination location.

16. The method of claim 15 , further comprising transmitting third information that enables a user device to display a second user interface for obtaining second user input, wherein said second user input enables definition of a perimeter associated with a departure location.

17. The method of claim 13 , wherein said first user interface is a web interface.
