GPS

GPS is short for the Global Positioning System.The system provides accurate location and time information for an unlimited number of people in all weather, day and night, anywhere in the world.
I think the best words to describe the GPS are efficient and accurate.It's such a significant innovation that our personal lives and even the whole world will be out of control without it.
GPS has applicants in a number of fields.Now let's experience some of them.

TIMING
Precise time is crucial to a variety of economic activities around the world. Communication systems, electrical power grids, and financial networks all rely on precision timing for synchronization and operational efficiency. The free availability of GPS time has enabled cost savings for companies that depend on precise time and has led to significant advances in capability.
For instance.Power companie and utilities have fundamental requirements for time and frequency to enable efficient power transmission and distribution.By analyzing the precise timing of an electrical anomaly as it propagates through a grid,engineers can trade back the exact location of a power line break.

ROAD&HIGHWAYS
GPS often increase efficienicies and safety for vehicles using highways,streets,and mass transmit systems.
More effective monitoring to ensure schedule adherence, creating a transit system more responsive to transportation users needs.
Better location information with electronic maps to provide in-vehicle navigation systems is prepared for both commercial and private users.

SPACE
GPS is revolutionzing and revitalizing the way nations operate in space.From guidance system for cremed vehicles to the management,tracking,and control of communication satellite constellations to monitoring the earth from space.

AVIATION,MARINE&TRAIN
With continuous,reliable and accurate positioning information,GPS can provide safe,flexible and fuel-efficient routes for these transportation methods.GPS makes a great contribution to maintaining smooting flow of traffic,and minimize costly delays due to waiting for clearance for track use.

PUBLIC SAFETY & DISASTER RELIEF
GPS helps deliver disaster relief to areas in a more timely and accurate manner, saving lives and restoring critical infrastructure.
It also provides positional information about individuals with mobile phones and in vehicles in case of emergency.

RECREATION
Outdoor exploration carries with many intrinsic dangers like getting lost in unfamiliar or unsafe territory.GPS technology coupled with electronic mapping has helped overcome much of the traditional hardships associated with unbounded exploration.
Relying on GPS,outdoor adventurers now have the confidence of knowing precisely where they are at all times,as well as how to retrun to their starting point.

GPS keeps pace with the times and satisfies modern people's need of efficiency and accuracy.That's why it can be so successful as an innovation.
