A GPS device is a navigation device that captures signals and receives information from the GPS satellites. It uses this information to accurately calculate its geographical information. Hence, through the data of the GPS satellite and the different features of GPS devices, we are able to extract various information like:
- Maps displayed in human-friendly format
- Guided navigation directions via text or speech
- Possibilities of routes available to a destination and shortest route available
- Traffic maps – warnings on traffic congestion on a particular location
- Location of public utilities like restaurants, hospitals, churches, banks, schools and so on
- Playback of journey undertaken with accurate details on location, routes taken, stop points and time.
