US 7,412,325 B1 · System and method for selective navigation tracking

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.
