english for engineering, GPS (Global Positioning System) The Global Positioning System (GPS) is a space-based satellite navigation system that provides location and time information in all weather conditions, anywhere on or near the Earth where there is an unobstructed line of sight to four or more GPS satellites. The Global Positioning System (GPS) is a network of about 30 satellites orbiting the Earth at an altitude of 20,000 km. Wherever you are on the planet, at least four GPS satellites are ‘visible’ at any time. Each one transmits information about its position and the current time at regular intervals. By combining GPS with other technologies from robotics, self-driving cars are becoming cheap, and fully automated mines are being operated by big mining companies. By combining GPS with mobile communications, a whole new category of industry has sprung up: location-based services. The iPhone 4S was the first Apple product to use both GPS and GLONASS navigation. Europe (with Galileo) and China (with Beidou) are also working on similar systems. India and Japan are working on systems that are not “global”. These systems should all be fully operational by the end of the decade. With GPS being installed in phones, computers, cars and other high-value items, it is becoming much easier to track those items if they are stolen.
