Satelliitsõnumites

Satelliitsõnumites is an Estonian term used to refer to the content contained within messages transmitted by satellites. The word is a compound formed from satelliit (satellite) and sõnum (message) with the plural inessive ending -ites, literally meaning "in satellite messages". In technical and scientific contexts, satelliitsõnumites describes the data carried by the downlink, including telemetry, scientific payload data, and command sequences.

Typical components include health and status data (housekeeping), instrument measurements, time stamps, and mission-specific data. Telemetry is often encoded into standardized frames and packets according to CCSDS protocols, with error detection and forward error correction. Downlink formats vary by mission, but common features include packet headers, sequence counters, and data integrity checks.

In usage, satelliitsõnumites appears in Estonian-language documentation, mission reports, and academic articles to denote the data content observed in ground-station receives. It is also used in media reporting about satellite missions to describe what the satellite transmitted during a pass.
