When you’re flying from one place to another, you want to make sure you’re on the right path. That’s where GPS comes in handy. You’ve probably heard of GPS (Global Positioning System), it’s a map in the sky that tells pilots exactly where they are. But did you know that light technology, called photonics, is making GPS even better for airplanes?
Cleaning up signals
GPS uses satellites to send signals to planes, helping them know their exact location. But sometimes, especially in crowded cities or when there’s a lot of interference, those signals can get fuzzy. That’s where photonics comes in. It helps clean up those signals, making sure planes know exactly where they are at all times. So even when things get a little tricky, pilots can rely on their GPS to keep them on track.
Navigating without GPS
But photonics doesn’t stop there. It also helps with something called an optical gyroscope. It is a precise compass for airplanes. Instead of using magnets, it uses light to measure how fast the plane is turning. This helps pilots navigate even when GPS isn’t available, like when they’re making sharp turns or flying through bad weather.
Seeing through the fog
Photonics also helps with something called LiDAR. It’s like a special laser scanner that helps planes “see” obstacles and the ground below them. This is super important, especially when landing in foggy or mountainous areas. With LiDAR, pilots can make sure they’re landing safely, even when they can’t see very well.
Advancements in navigation technology Thanks to photonics, airplanes have supercharged navigation systems that keep passengers safe and sound, no matter where they’re flying. As technology continues to evolve, we can expect even more innovations in aviation navigation, ensuring smoother and safer journeys for travelers around the world.
