# Aerospace Yuxing (Emposat)

> Aerospace Yuxing (航天驭星; English brand Emposat Co., Ltd.; legally Beijing Aerospace Yuxing Technology Co., Ltd.) is a Beijing-headquartered commercial space-infrastructure operator founded in 2016 by a core team drawn from the China Academy of Space Technology and the wider CASC system. It builds and operates the ground segment commercial satellites depend on — more than 60 satellite ground stations worldwide plus the Ningxia Zhongwei remote-sensing calibration site — and sells telemetry, tracking and command (TT&C), on-orbit operations management, payload data reception, calibration, collision warning and debris mitigation as services.

**There is no Aerospace Yuxing API.** As of 2026-09-12 the company publishes no developer portal, no public API documentation, no SDK, no webhooks, and no machine-readable API contract (no OpenAPI, AsyncAPI, GraphQL SDL, Postman collection or JSON Schema) on any reachable host. Do not assume or invent `api.emposat.com`, `docs.emposat.com`, `developer.emposat.com`, `open.emposat.com` or `cloud.emposat.com` — none of those hostnames resolve. Every `/.well-known/` path and every contract-discovery path returns 404 on `www.emposat.com`; the apex `emposat.com` has no A record and the site publishes no robots.txt and no sitemap.

The one machine-facing surface the company advertises is not a web API. For long-term spacecraft operations management it offers a **center-to-center connection** to a customer's own operations center over space ground-segment protocols — **PDXP, CSP, KISS, CORTEX and AX.25**, plus customer-defined interface protocols. Those are link- and mission-layer protocols negotiated in a contract, not something an agent can call. There is also a customer service portal at `https://service.emposat.com/#/cloud`, which is a login surface for existing customers and did not answer at all from a US probe.
