👉 A rocketsonde, also known as a high-altitude sonde or satellite sonde, is a type of underwater sonde used to measure fluid properties such as temperature and pressure. It works by using a high-pressure probe that penetrates the water column at a depth of about 10 kilometers (6 miles) below surface. The probe then emits ultrasonic waves into the water, which can be detected through the reflection from the bottom of the ocean or the surface of the ship. This
