What does GPS mean in ASTRONOMY

What Is GPS?

GPS works by sending signals from orbiting satellites to receivers on the ground. The satellites carry atomic clocks that provide accurate timing information. By measuring how long it takes for signals to reach different receivers, a device can calculate its location and altitude relative to the satellite positions. When you turn on your GPS receiver (like when you open up Google Maps or any other map app), the receiver starts looking for at least 3-4 satellites in orbit with good signal strength. Once it finds them, it uses their data to accurately calculate its position within a few meters so that you can see where you are on a map while navigating through unknown locations.

Benefits Of Using GPS

The main benefit of using GPS is its accuracy and precision compared to traditional navigational methods such as maps and compasses which are notoriously unreliable due to human error and changing terrain features over time. With GPS guiding you form one point to another in an unfamiliar area will almost always be accurate thanks to the millions of kilometers worth of satellite data available at any given moment for calculation purposes. Furthermore, GPS allows drivers (or pilots) to navigate complex roads with ease — something which would be impossible if relying solely on maps or memory alone.

In addition to navigation, there are many other ways that people use GPS technology including tracking shipments or large fleets of vehicles such as buses or trucks; finding lost hikers/skiers; identifying hibernating animals; monitoring endangered species movements; detecting natural disasters like floods, earthquakes or tsunamis; and surveying remote areas inaccessible by roadways just name a few applications!
