Run your ground station network from one console.

Umoja is software-defined mission control for satellite ground operations. Schedule passes, stream live telemetry, and pull mission data across Remos and third-party stations. No hardware to buy, no procurement cycle.

The whole pass lifecycle, in one portal.

Everything the portal does is available over the API, because the portal is built on the same endpoints you get.

One timeline for the whole network

Every station's booked, live and upcoming passes on one shared axis. Book in a click; the scheduler keeps it conflict-free and scoped to your group.

Every station on one axis
Conflict-aware booking
Bulk and API-driven scheduling

Umoja's pass schedule: five satellites with booked downlink windows across one afternoon — Passes on one shared timeline

Be in the room for every pass

Live spectrum, waterfall, IQ constellation and the antenna sky-track stream the moment a pass goes active, with TM/TC counts and the current doppler shift.

Frame-accurate, zero-copy
Antenna and ephemeris track
TM/TC counts and live doppler

Umoja's live pass view: spectrum, IQ constellation, waterfall, sample distribution, link status and the antenna sky position — A pass in progress, ten minutes from loss of signal

The portal is just one API client

Mint a per-tenant key and drive scheduling, live streams and data retrieval from your own mission systems, or bridge straight into Yamcs and COSMOS.

Bring your own ground segment.

Umoja runs the stations you already have, not only the ones you buy from us.

Any station, one network

Native to every Expedite modem; connects to third-party antennas, modems and GSaaS networks too.
Mission-data archive

Every recording and downlink, searchable, with signed download links that expire.
Secure self-service

Accounts with two-factor authentication, group-scoped visibility, and per-tenant API clients you provision yourself.

Speaks the standards you already run.

No adapter layer to write, and nothing proprietary between your spacecraft and your data.

Build against it.

The reference is generated from the running service on every release, so it cannot drift from what the API actually does.

25 endpoints across Satellites, Stations, Transceiver.

Bring your ground segment into software.
