Internet search leader Google introduced new location service to mobile phone users which can automatically informs users where they are on a map, media reported Thursday.

The mapping system that uses cell phone towers to let mobile phone users simply type the number "0" on their phone to move the map to their approximate location.

The service relies on a database of cell towers Google has constructed by using anonymous readings of mobile signals from previous Google Maps users to help locate My Location users.

Google's new My Location service is being offered in test mode to U.S. users and is designed to expand the percentage of cellphone users of location-aware services, whether or not their phones come equipped with satellite-locating chips.

Google is offering the service for free, direct to U.S. consumers, and is expected to eventually introduce local advertising that takes advantage of the location-aware service. The company has created the service independent of carriers.
