transponder
transponder is one satellite receive-transmit chain that carries a bundle of TV channels on a single downlink frequency; KingOfSat European Satellite Zapping & Directory: coverage.granularity reads records "Per-channel and per-transponder rows grouped by satellite orbital position". In Datadory's catalog of 1,744 datasets, KingOfSat European Satellite Zapping & Directory: coverage.granularity reads and KingOfSat: are working examples.
What is transponder?
A transponder is one satellite receive-transmit chain that carries a bundle of TV channels on a single downlink frequency.
In these catalogs it is the grouping tier between satellite orbital position and channel row.
In this catalog it appears concretely: - KingOfSat European Satellite Zapping & Directory: coverage.granularity reads — "Per-channel and per-transponder rows grouped by satellite orbital position". - KingOfSat:. - SatIndex Daily Transponder Scan Database: coverage.granularity — "Per-channel rows grouped by frequency/transponder per satellite". - SatBeams Satellite Coverage & Channel Database: coverage.granularity — "Per-satellite, per-beam/footprint, per-transponder channel rows".
Why does transponder matter when choosing a dataset?
Conventions decide whether two sources can be joined at all. Buy one side of an analysis that ignores this convention and every reconciliation step — calendar alignment, unit conversion, entity matching — lands on your team instead of the vendor's.
The failure mode is concrete: a source can carry the transponder label while differing from what you need on exactly the dimension that matters — Per-channel and per-transponder rows grouped by satellite orbital position. Comparing two sources on that line usually settles the choice faster than any feature matrix.
You rarely have to take a vendor's word for it. 82.4% of the 1,744 datasets Datadory catalogs are free to access, and KingOfSat European Satellite Zapping & Directory: coverage.granularity reads lets you inspect the real artifact before any budget is committed.
How do you evaluate transponder in a data source?
Treat every claim of this attribute as testable:
- Open KingOfSat European Satellite Zapping & Directory: coverage.granularity reads and confirm its record — "Per-channel and per-transponder rows grouped by satellite orbital position" — against the files you actually receive.
- Open KingOfSat: and compare its listing against the delivered artifact before paying for a commercial equivalent.
- Open SatIndex Daily Transponder Scan Database: coverage.granularity and confirm its record — "Per-channel rows grouped by frequency/transponder per satellite" — against the files you actually receive.

Frequently asked questions
What is an example of transponder?
KingOfSat European Satellite Zapping & Directory: coverage.granularity reads is the clearest example in this catalog. Its record states: "Per-channel and per-transponder rows grouped by satellite orbital position". Across all 1,744 datasets Datadory averages a quality score of 7.81 out of 10, so a named example can be weighed rather than trusted blindly.
Is data described as "transponder" free to use?
Treat access and permission separately. 82.4% of the 1,744 datasets in this catalog are free to access, but 235 are freemium and 61 are paid outright, so confirm both the price and the license on the exact distribution before building on it.
How do I verify a source really provides transponder?
Open KingOfSat European Satellite Zapping & Directory: coverage.granularity reads next to KingOfSat: and compare the promise with the download. Field definitions are verified for 1495 of 1,744 datasets (85.7%), which makes that check fast inside the catalog and manual outside it.
