Early-stage players we’re tracking — real enough to watch, too early to catalogue. Tech demos, first hops, filed constellations without an orbital track record yet. Each one joins the live catalogs the moment it clears the bar.
A debris-resistant LEO network pitched at up to 300,000 satellites, filed via Rwanda — sustainability as the core differentiator.
A planned 600-satellite Ka-band “Outernet” for secure enterprise and government data, laser-meshed in LEO.
A 791-satellite MEO/HEO “edge-computing” network, opening with a 32-satellite first phase (8 HEO + 24 MEO).
Australia’s first home-built orbital rocket — Eris, a small-lift vehicle using hybrid propulsion.
The automaker’s experimental reusable-rocket program — its first move into launch.
An experimental reusable-booster demonstrator; feeds the JAXA–France–Germany CALLISTO program.
A reusable, returnable satellite bus (Delphi, ~200 kg, ~25% payload) — a platform company, not a constellation operator.
A hand-picked list of early-stage space players — filed constellations, pre-orbital / R&D rockets, and new satellite platforms — that are real enough to track but too early to catalogue as a live operator or launch provider. Each entry joins the live catalogs the moment it clears the bar.
An entry is on the watchlist if it is an announcement, filing, or tech demo with no established flying operation and no concrete near-term deployment. Three kinds: a filed constellation (a spectrum filing / stated plan, no active satellites yet); a pre-orbital or R&D rocket effort (a hop test, a reusable-booster prototype, a failed maiden flight); and an early satellite-platform or other company that fits neither the operator nor the launch-provider catalog.
Entirely editorial and hand-curated in src/lib/watchlist-catalog.ts. Every entry carries a primary source link; the “latest”, “next” and funding figures are the companies’ own stated numbers, summarised — not independent estimates. The only live input is the CelesTrak active count for a filed constellation, used to detect when it joins the catalog (see below).
A filed-constellation entry is also held in the operator catalog and hidden from the Constellations directory while its active satellite count is zero. The moment CelesTrak reports satellites matching it, its count rises above zero and it moves to Constellations automatically — dropping off the watchlist in the same step. The display location is decided live by the data; the catalog entry never changes. Rocket and platform entries join the catalogs by editorial judgement (an orbital flight, a concrete constellation) into Launch providers or Constellations.
Companies and programs with public, sourceable activity but no orbital track record yet, deliberately kept off the live catalogs so those stay a record of what is actually flying or concretely deploying.
Anything already flying or concretely deploying (that lives in Constellations or Launch providers), and speculative efforts with no sourceable activity. Some pre-launch names that do clear the bar — Reflect Orbital and Open Cosmos (concrete constellations), Skyroot (a company-level launch provider) — sit in the live catalogs, not here.
The list is intentionally small and selective, not exhaustive — it reflects editorial judgement about who is worth watching, and dates / figures can lag fast-moving early-stage companies. The automatic move to Constellations only fires if a filed constellation’s eventual satellite names match its pre-registered pattern; the first launch may need a one-time pattern tweak if the real object names differ.
