GPS is like getting help from a friend to find your way faster.
Normal GPS is like asking a friend who's a little far away for directions, they take a few seconds to think and reply, so it takes longer to know where you are. Assisted GPS, on the other hand, is like having a friend right next to you who already knows part of the way, they help you get started much quicker.
How They Work
Normal GPS has to figure out your location all by itself. It listens to signals from satellites in the sky and does some math to know where you are. This takes time, like waiting for a friend to count out loud before giving directions, maybe 30 seconds or more.
Assisted GPS gets help from your phone or device. It uses information it already knows (like your approximate location from Wi-Fi or cell towers) to guess where you might be. That means it doesn’t have to do as much math, and it can give you a location faster, sometimes in just a few seconds.
It’s like the difference between drawing a map from scratch and using a partly filled-in map to find your way quicker.
Examples
- A phone with Assisted GPS finds your location faster than one without it because it uses help from the internet.
- Assisted GPS is like getting directions from a friend who knows the way, while normal GPS has to figure it out on its own.
- When you use maps on your phone, Assisted GPS helps you get there quicker than regular GPS.
