Planned fleet

~100 satellites (company target as of an April 2026 funding round); a 5–9-satellite batch was manifested on a Falcon 9 Transporter-18 rideshare for October 1, 2026, but hadn't appeared in this report's tracking data as of its most recent run — either not yet flown or not yet catalogued.

Sateliot's four tracked satellites all launched together on a single Falcon 9 rideshare in August 2024, so they sit in nearly the same orbital plane — that's why the timeline above shows tight trains of 2–4 passes a few minutes apart, then a long gap until the next orbit brings that plane back around. A sun-synchronous polar orbit like this one crosses close to every latitude on Earth, poles included, roughly once per orbit — unlike AST SpaceMobile's or Lynk's lower-inclination orbits, it doesn't avoid high-latitude ground stations the way theirs can, it's just infrequent because there are still only four satellites in one plane. Closing the gaps between trains means adding satellites in more orbital planes; Sateliot has publicly targeted on the order of 100 satellites for that, though the timeline has slipped before. A second batch was reportedly manifested for an October 2026 rideshare — once a launch in a different plane actually shows up in tracking data, the long gaps between trains should start closing.

Company facts last checked October 2026 — orbit/altitude/plane count above are computed fresh from this run's TLEs, everything else in this box is hand-researched and can go stale faster than the orbital data does.

Summary

Over the next 4 days, a satellite is above 10° elevation 11.78% of the time (28.8 passes/day, median 6.9 min each). At a more realistic 25° link margin that drops to 3.8%, with gaps up to 12.4 h where nothing is reachable at all.
