What telemetry information is typically transmitted by satellite beacons?

Satellite beacons are continuous or periodically repeating signals transmitted by an amateur satellite. Their primary purpose is to help ground stations locate the satellite, easily determine the Doppler shift of the signal, and receive telemetry data. Telemetry is the transmission of internal measurements taken by the satellite sent back to operators on the ground. This data typically includes the health and status of the satellite, such as battery voltage, solar panel current, internal temperatures, and the operational status of its transponders. It does not generally broadcast time of day or the received signal strengths of individual users.
