System, method and apparatus for communicating position data |
摘要 |
A method on a computer unit for calculating and transmitting position data is disclosed. The method includes monitoring motion of the unit. If motion of the unit is detected, the method further includes initiating a start sequence of the unit, calculating current position data of the unit using the Global Positioning System (GPS), calculating a difference between the current position data of the unit and a previous position data of the unit and transmitting the current position data of the unit if the difference is greater than a threshold value.
