System and method for selective navigation tracking
First Claim
1. A method of providing positional information, said method comprising:
- sending from a mobile device to a receiving device selected by said sending mobile device at least one current navigational position of said mobile device,at said receiving device determining from received ones of said current navigational position of said sending mobile device if said mobile device and said receiving device are physically converging; and
at said receiving device and based upon a determination of convergence, providing to a user of said receiving device an estimated time of convergence of said mobile sending device and said receiving device.

Abstract
There is disclosed systems and methods for controlling the communication of navigation positioning information from a source of the information to another device for tracking purposes. In one embodiment, a user having a communicating device that maintains a record of its present location establishes a communication link to one or more selected targets and then grants permission to his/her device to continually send updates of his/her device'"'"'s position to the selected other devices. When the devices are converging, the receiving device can display the FTA of the sending device. These updated communications can be on a data channel of a voice communication device if desired.
