Global Positioning System or GPS has found its way to human everyday lives in a number of ways not previously possible. It has managed to save lives and property all over the world. It played a big part in rescue operations of trapped miners as GPS receivers were quick to determine the nearest police car, fire truck or ambulance to an emergency. Mapping, construction and surveying companies rely on GPS receivers to check their positions to make sure that a straight tunnel, for example, is made rather than a crooked one. Mine operations use GPS for safe navigation of mining equipments when visibility is obscure.
Automobile manufacturers offer moving-map display guided by GPS receivers as a feature in new vehicles. Archeological, biologists and explorers use GPS systems to locate ancient ruins, migrating animals and herds and endangered species. The future of GPS is only limited by one’s imagination.
