# Transit & broadcast

> Adapter-mostly SDKs: satellite ground segments, in-flight entertainment, maritime IPTV + VTS.

The transit and broadcast SDKs are **adapter-mostly** — thin
operator-side wrappers that translate established vendor
vocabularies (Dialog / iDirect, Panasonic eX3, Tripleplay, IALA VTS)
into the EnfinitOS substrate-agnostic vocabulary.

<Note>
  **Publish at launch.** All three SDKs (satellite, aviation, maritime)
  publish at the April 2027 production launch. They are typed, tested,
  and integration-ready; adapter wiring is complete. Vendor-side
  endpoints and any remaining operational hardening are finalised at
  customer integration time. Sandbox access is available now at
  [enfinitos.com/apply](https://enfinitos.com/apply). Reach out before
  committing to a production integration on these substrates.
</Note>

## Satellite

```sh theme={null}
npm install @enfinitos/sdk-satellite
```

Dialog / iDirect + Comtech ground-segment adapters. Translates
carrier / MODCOD / footprint / Es/N0 / BER into the substrate-
agnostic `BroadcastFootprintClaim` and proof events.

ITU, FCC, Ofcom compliance modules wrap the spectrum and footprint
constraints. The full SDK is on the
[public developer hub](https://enfinitos.com/developers/satellite).

## Aviation

```sh theme={null}
npm install @enfinitos/sdk-aviation
```

In-flight entertainment adapters — Panasonic eX3, Thales AVANT,
Anuvu Open Sky. ARINC 763 / 836 vocabulary translated for the
EnfinitOS plane.

The aviation SDK reports per-flight playback windows and respects
sky-wide content policies. See
[/developers/aviation](https://enfinitos.com/developers/aviation).

## Maritime

```sh theme={null}
npm install @enfinitos/sdk-maritime
```

Cruise IPTV (Tripleplay, GuestCast), port-side IALA VTS, and
Inmarsat Fleet Xpress / Iridium Certus uplink shims.

The maritime SDK enforces the **GMDSS refusal list** — safety
channels (GMDSS\*, DSC\*, EPIRB\*, SART\*, VHF-CH16\*, VHF-CH70\*,
406MHZ\*) can never carry commercial inventory regardless of policy
configuration. This is a hard-coded refusal at the SDK layer.
