Thor‑5 Transponder Telemetry / Beacon Carriers These signals are narrowband technical carriers transmitted by the Thor‑5 satellite in the Ku‑band, close to 11700 MHzMegaHertz (MHz) 10^6 Hz. They are part of the satellite’s TT&C (Telemetry, Tracking and Command) and beacon system.

Key characteristics Type of signal: CWContinuous Wave or narrowband FSKFrequency-Shift Keying The carriers are transmitted as continuous‑wave (CWContinuous Wave) tones or very lightly modulated narrowband FSKFrequency-Shift Keying. They do not use DVB‑S or DVB‑S2 modulation and carry no broadcast content.

Purpose: TT&C and antenna alignment These carriers support satellite control functions, including telemetry downlink, frequency reference, and precise antenna pointing for ground stations.

Stability: highly frequency‑stable The tones are generated by the satellite’s internal reference oscillators and are designed to remain stable for long‑term tracking and monitoring.

Visibility: always-on technical signals They are transmitted continuously and independently of commercial transponder activity, making them reliable markers for identifying the satellite.
