telemetry
- Data transmitted from a spacecraft to a ground station reporting the status of onboard systems — including power levels, temperatures, attitude, orbital parameters, and subsystem health. Part of the telemetry, tracking, and command (TT&C) function.
- Telemetry links are typically allocated dedicated spectrum in S-band or X-band and are among the first communications established after launch. Loss of telemetry is one of the earliest indicators of a spacecraft anomaly.
