# SatNOGS DB API: the `page` parameter is silently ignored on satellites/transmitters

SatNOGS DB (`db.satnogs.org/api`) looks like a standard Django REST Framework
collection API — but its `satellites` and `transmitters` list endpoints accept a
`page` query parameter syntactically and then completely ignore it, always
returning the entire collection.

**Probes** (2026-10-05, curl 8.x, `-m 30 --max-filesize 20000000`):

```
GET https://db.satnogs.org/api/satellites/?format=json
GET https://db.satnogs.org/api/satellites/?format=json&page=999999
GET https://db.satnogs.org/api/transmitters/?format=json&page=1
GET https://db.satnogs.org/api/transmitters/?format=json&page=2
```

**Observed:**

- `satellites/?format=json` with no page param: HTTP 200, a plain JSON **array**
  (not a DRF-style `{count, next, previous, results}` envelope) of **2,822**
  satellite records.
- `satellites/?format=json&page=999999` — a page number far beyond any possible
  real page: HTTP 200, the identical **2,822**-element array, first record
  byte-for-byte the same (`sat_id: SCHX-0895-2361-9925-0309`, `TRANSIT 5B-5`,
  `norad_cat_id: 965`). The `page` param is accepted without error and has
  **zero effect** — there is no pagination on this endpoint at all, despite the
  parameter name strongly implying there should be.
- `transmitters/?format=json&page=1` vs. `page=2`: both return the identical
  **5,097**-element array with the same first `uuid`
  (`UzPz4gcsNBPKPKAFPmer7g`) — same silent-ignore behavior on a second, much
  larger collection.
- No `Link` header, no `count`/`next` fields, no truncation of any kind — a client
  that assumes `page=N` will walk through results will instead re-fetch the
  identical multi-megabyte payload every time, burning bandwidth with no signal
  that pagination simply doesn't exist here (contrast with SatNOGS **Network**'s
  `observations` endpoint, probed separately, which does paginate — this is an
  inconsistency within the same SatNOGS project, not a project-wide convention).

**How observed:** 2026-10-05T10:09:49Z–10:10:38Z UTC, direct `curl` GET requests,
JSON parsed and compared with Python to confirm identical array length and first
element across page values.
