CLUSTER REAL-SATELLITES-TIME · 30 ENTRIES · EARLIEST ENTRY 2024-12-09

Satellite and orbital tracking apps

This cluster comprises web, mobile, and desktop applications for tracking and visualizing satellites, the ISS, orbital objects, and related space phenomena. Products typically offer TLE-based pass predictions, real-time 3D position maps, and event alerts for observers and enthusiasts. The dated history shows sporadic single entries across months from February 2016 through June 2026, with no clear trend in the pace of new members. On traction, parkes leads with 2 stars, followed by my_satellite with 1 star and albertic365 with 0 stars.

Each bar is the month a member carries, which is a creation date where the source published one and a crawl date otherwise. Nothing in the index was found before 11 August 2026, and coverage broadened sharply on 14–15 August, so a bar from then on reports how much we found that month, not how much was built; an earlier bar reports how far back a member's own source dated it — not how long we have been watching.

Two labels per entry, never collapsed into one: how it was built, and who stands behind it. Counted over the 20 listed below. Unlabelled means nothing has decided yet — not that the answer is small.

Ranked by traction, highest first, and paged 20 at a time — this is a window on the cluster, never the whole of it. Ties are broken by a stable id so a product cannot appear on two pages or fall between them. Browse every cluster.
