A beacon is a distinct and identifiable signal transmitted by a satellite to indicate its presence or provide essential tracking information. Beacons play a crucial role in satellite tracking, monitoring, and communication systems.

Satellite beacons serve multiple purposes and are designed to facilitate various functions. They are typically used to establish and maintain contact with ground stations, enabling precise tracking and monitoring of satellite positions and movements.

The primary purpose of a beacon is to provide a unique identification signal for the satellite. By transmitting a specific code or pattern, the beacon allows ground stations to quickly identify and differentiate the satellite from others in space. This identification is vital for tracking and monitoring purposes, as it enables accurate and real-time updates on the satellite’s position, velocity, and other vital parameters.
