WAAS
WAAS (Wide Area Augmentation System) is a system used for making GPS (Global Positioning System) more accurate. Let's imagine you are trying to find a treasure with a map. Normally, the map may not be 100% accurate and you might get lost or not find the treasure. This is like normal GPS which can also be a bit off sometimes.
But with WAAS, it's like having someone else with the map who is telling you exactly where to go. WAAS has special stations on the ground that send signals to GPS satellites, telling them to correct any slight errors in location. Like having someone double-check your map and make sure you're on the right track. This means that you can find the treasure (or your location) more easily and accurately.
WAAS is great for pilots who use GPS to navigate airplanes or for people who need very accurate location information for things like farming or surveying land. It's like having a super-helpful map that always guides you in the right direction!
