Orbital compute: what is flying, what is filed, and what silicon is on board

14 satellites tracked (10 compute-class, 4 demo-class), 6 pending catalog resolution, and 7 filed constellations totalling 1,145,480 claimed seats. Every count derives from the desk's registry at render time.

How to read the three states

Tracked - a satellite with a public catalog entry and a two-line element set we hold. It is flying; we can point at it.
Pending - launched or announced, not yet resolvable in the public catalog by name. Chinese launches lag the US catalog by days to weeks, and some objects are never named publicly.
Filed - a constellation filed with a regulator. Paper seats, never spacecraft.

Silicon on board (tracked fleet)

NVIDIA Jetson Orin: 10 satellites
NVIDIA H100: 1 satellite
UNDISCLOSED: 1 satellite
Intel Movidius Myriad X VPU: 1 satellite
Ubotica CogniSat AI processor: 1 satellite

Data-center GPUs in orbit: 1 - STARCLOUD-1 (Starcloud). Everything else flying is edge silicon, stated as such in the table.

Filed: paper constellations

Seats are reservations filed with a regulator, not spacecraft. Not one of these orbits is drawn anywhere on our maps.

What this page cannot see

The Chinese compute fleet is name-blocked in the public US catalog. The Three-Body group-02 satellites, the ADA Star Compute satellites and the MetaX-gpu satellite have flown, but most resolve to no catalog name, so they are not counted as tracked here.
Board silicon is undisclosed or unrecorded on 4 objects listed on this page. Those rows say so rather than guess.
Inter-satellite topology is unpublished by every operator tracked here. Group-level statements (an optical mesh, a relay layer) are quoted as the operator's claim; no per-pair link is drawn.
Counts are not a census. This page covers satellites carried in the desk's registry, which is built from launch records and filings, not from a global object catalog sweep.

Where this sits

the orbital lens - every tracked object plotted from its own TLE | the buildout ledger - the ground side of the same buildout | company records | methodology

Derived from the desk's orbital registry at render time. Launch records and filings carry their own sources on the company records. Someday every one of these rows will be stale; the registry is refreshed monthly and the page with it.
