The GPS (Global Positioning System) originally used for military purpose, however GPS is considered as a dual-use technology, means it has considerable for civilian purpose as well.
Global Positioning System applications generally fall into 5 main categories:
- Location – determining a position.
- Navigation – getting from one location to another
- Tracking – monitoring object or personal movement
- Mapping – creating maps of the world
- Timing – bringing precise timing to the world
GPS is a great and reliable tool for businesses and organizations in many industries, agriculture, scientist, transportation, mining, surveyors, financial services, autonomous vehicle, mobile communication, aviation, military, fishing, sales and services, these are few examples of industries that used GPS.
There are also some of the people who use GPS on daily basis for work. GPS works at all times and almost in any weather conditions. They use GPS information to prepare accurate surveys and maps, tracking location or position, taking precise time and for navigation.
GPS also being used for public safety and disaster relief. It saves lives by preventing transportation accidents, support search and rescue efforts, and speeding the delivery of emergency services and disaster relief.
GPS is vital to the Next Generation Air Transportation System (NextGen) that will enhance flight safety while increasing airspace capacity. GPS also advances scientific aims such as weather forecasting, earthquake monitoring, and environmental protection.
Nowadays, everyone from doctors, dispatchers, scientists, athletes, farmers, soldiers, pilots, hikers, delivery drivers, pilots, sailors, fishermen, and people from many other fields are using GPS systems in ways that make their work more productive, safer, and easier.
In every case, uses of GPS are based on measuring the individual’s distance from multiple satellites. GPS is just one of several groups of satellites used to determine a position. Galileo, GLONASS, BeiDou and GPS are the four main satellite constellations used worldwide.
