It’s 10 p.m. Do you know where your children are?

With a new service from Verizon Wireless, you will.

Using the Global Positioning System chips mandated in wireless phones by the Federal Communications Commission, parents whose children have wireless phones, such as the LG Migo, will soon be able to use a service, to be named Chaperone, to track their location in real time.

The service is expected to cost between $10 and $15 per month when it becomes available in May 2006, according to news reports.

Joe Astroth, vice president of location based services for Autodesk, the company supplying the location tracking software to Verizon Wireless, said that parents would be able to locate their children to within a few yards using a Web site, or receive a text message if the child leaves a predefined geographic area.

Verizon also expects to launch a location-based service for adults, called Navigator, which will provide turn-by-turn driving directions, he said.
