What is a satellite beacon?

A satellite beacon is a transmission originating from a satellite that provides essential information about the satellite's status, orbit, and operational parameters. This information is valuable for users on the ground who may be trying to communicate with the satellite or track its position. The beacon can include data such as the satellite's identification, its operational status, and telemetry data, enabling users to determine the satellite's current condition and helping them to orient their equipment correctly.

The primary functions of a satellite beacon include aiding in tracking the spacecraft and providing operators and enthusiasts with real-time data that can be crucial for effective communication and operation. By providing this information, beacons serve as a vital tool for both amateur radio operators and professional satellite uplink stations.
