Using satellites, a system called GPS or Global Positioning System has been revolutionized into the modern world. Using satellite navigation, you can predict with accuracy the exact destination of a vehicle traveling at high speed through the streets. How GPS Navigates You through Your Journey In this example, we will see how NASA has successfully used satellites to map out the Earth's surface using images. In fact, NASA is able to obtain images of almost the entire surface of the Earth at least at one point in time. Using satellites, the maps could be updated continuously without any gap. GPS systems In fact, GPS systems are extremely accurate. If the driver follows a particular road for some time, the system can always find the precise place to avoid road rash accidents. Furthermore, GPS technologies are also reliable and effective. In other words, technology can provide people with safe routes through real situation
