The many interesting and unexpected ways scientists use GPS

GPS is not just for your car or phone.

You know you can use global positioning system (GPS) to navigate around your city, but did you know that it is also used to predict how bad a tsunami can be, to warn people of sudden floods, to measure the drying up of a forest during a drought, or to map the ocean floor? Yes, indeed GPS has many different applications.

This is particularly impressive, given that all GPS systems are served by only 31 satellites orbiting space. Cars, telephones and other instruments on Earth pick up signals from a satellite and determine how far they are from it.

Then, using four other satellites in the same way, they can determine exactly where on Earth the receiver is located. It should also be noted that scientific instruments have an extremely precise receiver that can determine their location up to a few millimeters compared to those that phones can make from one to 10 meters.

Scientists are getting very creative with GPS receivers using them for all kinds of missions. What are these missions? How exactly do they use GPS systems? How accurate are the data they measure? How useful are its results for society and the planet? We answer all these and more questions in our video.
