How long does it take for a PLB to provide position accuracy?

Personal Locator Beacons (PLBs) are vital safety devices designed to send distress signals to search and rescue authorities when activated. The specified time it takes for a PLB to provide position accuracy is crucial for effective search and rescue operations.

In this context, it typically takes about 90 minutes for a PLB to accurately determine and report the user's position. This time frame is necessary to ensure that the satellite system can triangulate the signal effectively, considering factors such as satellite movement and signal processing. Once the signal is received by rescue authorities, they can utilize this precise information to coordinate an effective response.

This time frame can vary depending on specific conditions such as atmospheric factors and the operational status of satellites. However, 90 minutes is generally recognized as the standard period for reliable position accuracy following activation of the device.
