Underwater acoustic positioning system
An underwater acoustic positioning system helps people find things underwater. It sends sound signals through the water to find the location of objects like sunken ships or lost treasure.
Imagine you are playing a game of hide-and-seek. You close your eyes and count to ten while your friends hide. Then you have to find them. A positioning system works the same way. Instead of counting to ten, the system sends out sound signals into the water.
The sound signals are like a message that bounces back when it meets an object in the water. The positioning system listens for these messages and tells you where the object is by showing you on a map or screen.
Underwater acoustic positioning systems are used by scientists to study the ocean and by submarines to navigate. They can also be used by fishermen to find schools of fish.
