Gps devices have been used for everything from tracking stolen cell phones to monitoring earthquakes. And now they are being used to help fix potholes. In Omaha, Nebraska, the roads are apparently so rough that the mayor has implemented a new system that uses gps to make the neighborhood roads smoother for residents. Although city work crews have been responding to complaints about potholes, they are having a hard time finding all the rough spots. The Omaha mayor claims this new system will help the city workers be more successful in their attempts to keep the roads safe. The city is making gps devices available to neighborhood residents so that when they drive, they will be able to pinpoint the exact locations of the potholes. The city crews will use maps of neighborhoods and the pothole information provided by the gps tracking devices to fill in the holes more efficiently.

While this pothole patrol system is unique to Omaha, it illustrates the rapidly expanding use of gps systems. This space-based navigation system plays an important role in modern life. Gps devices are used in both the public and private domain. For example, many airlines now use gps devices for navigation and landing assistance. Scientists use gps devices to study and gather data. And many police and detective forces use gps to track criminals or stolen goods. In the private sector, many individuals have gps systems attached to their cars or cell phones. Others use gps devices to ensure the safety of a loved one.
Gps, short for global positioning system, was established in 1978 by the U.S. Department of Defense. Although it began with only one satellite, there are now 24 satellites that orbit the earth twice a day. These satellites send radio-wave signals back to receivers on the earth. Although gps devices can be affected by the atmosphere and other factors, they are extremely accurate, able to pinpoint the location of an object or person to within 15 meters.
Although it has only been available for public use for the past three decades, gps equipment plays a huge role in daily life today. Used for tracking criminals, finding stolen vehicles, and now helping to fix potholes, these reliable devices make daily life easier and provide solutions to many probl...
