GNSS positioning calculation
Okay, imagine you have a magic map in your hand that tells you exactly where you are and where you want to go. But how does the map know where you are? That's where GNSS (Global Navigation Satellite System) comes into play.
GNSS is like having a bunch of satellites (spaceships in space) that send signals down to Earth. Your phone or GPS device receives those signals and uses them to figure out where you are. Think of it like a treasure hunt. The satellites are hiding little treasures (signals) and your phone tries to collect as many of them as possible.
But how does your phone know where it is on the map? With GNSS positioning calculation, your phone takes the signals it collected and calculates the time it took for those signals to travel from the satellites to your phone. Since the signals travel at a known speed, your phone can figure out how far away it is from each satellite. Once it has the distance, it can use something called trilateration to determine its exact location on the map.
To put it simply, GNSS is like having a bunch of friends who tell you where they are by shouting really loud. Your phone listens to their shouts, figures out how far away they are, and uses that information to pinpoint where it is on the map. Now you can find your way to your destination, just like a treasure hunter!
