Why does SONAR use satellites?

SONAR (Sound Navigation and Ranging) primarily uses sound waves to detect and locate objects underwater, while satellites are employed for various complementary purposes. Satellites can provide critical data such as oceanographic conditions, surface features, and weather patterns, which enhance the effectiveness of SONAR operations. Additionally, satellite positioning systems like GPS help accurately determine the location of SONAR-equipped vessels, improving navigation and data collection. Thus, the integration of satellite technology enhances the overall efficiency and accuracy of SONAR applications.
