Sprint customers will soon get GPS-enabled navigation service for free as part of certain data packages.

The service will be available to customers with Power Vision data plans starting at $20 a month, and it comes in a package that also includes Internet browsing, digital radio and streaming video.

Navigation services are enabled by global positioning satellite, or GPS, technology. Phones are embedded with GPS chips, which receive signals from low orbiting satellites. The satellites then track the location of these devices.
