Underwater Locator Beacons (ULBs) are critical devices used to locate submerged objects, especially in search and rescue operations involving aircraft, ships, and offshore installations. These small, battery-powered devices emit acoustic signals when activated, helping divers, rescue teams, and underwater vehicles pinpoint the exact location of submerged wreckage or equipment. ULBs are particularly vital in aviation accidents, where they assist in locating black boxes beneath the ocean surface, and in offshore drilling, where they help recover lost equipment. As technology advances, ULBs are becoming more sophisticated, durable, and reliable, ensuring faster recovery times and improved safety outcomes.

How It Works
How It Works
Activation: When a crash or accident occurs, the ULB is activated either automatically upon impact or manually by crew members. This triggers the device to start emitting acoustic signals.
Signal Transmission: The beacon sends out a high-frequency acoustic GS, typically in the 37.5 kHz range, which can travel long distances underwater.
Detection: Search teams or autonomous underwater vehicles (AUVs) equipped with hydrophones detect these signals. The signals help locate the precise position of the submerged object.
Location Confirmation: Multiple detections allow triangulation, confirming the exact location of the device. This process is crucial in deep or murky waters where visibility is limited.
Recovery: Once located, divers or remotely operated vehicles (ROVs) retrieve the object, often with the help of GPS and other navigation tools for accuracy.
Post-Recovery Analysis: Data from the ULB can be analyzed to understand the circumstances of the incident, aiding investigations and safety improvements.

Uses and Applications
Uses and Applications
ULBs are primarily used in aviation, maritime, and offshore industries. In aviation, they are embedded in black boxes to aid in crash investigations. Maritime applications include locating sunken ships, aircraft wreckage, and submerged equipment. Offshore oil and gas operations utilize ULBs to recover lost tools or components, minimizing environmental risks. Search and rescue teams rely on these beacons to reduce search times significantly, especially in challenging underwater conditions.
