URGENT: We ran out of 5-digit catalog numbers with the addition of Saramago on 2026-07-11. We had estimated that to occur around 2026‑07‑12 back on 2026-05-09. The official USSF SATCAT is now at 100684. All newly cataloged objects will have 6-digit catalog numbers of 100000+ and GP data will not be available for them using the TLE format. CelesTrak developed new formats that removed the 5-digit catalog number limitation (and finally fixed the Y2K problem) in May 2020 and immediately began providing GP data in those formats for software developers. Please be sure to adhere to our usage policy when retrieving any CelesTrak data. The same limitations apply to the legacy fixed-field SATCAT. That legacy format will continue to update but will only contain data for objects with catalog numbers below 70000. Be sure to follow @TSKelso on Bluesky for the latest updates, tutorials, and changes as we move forward. Spread the word! ‑ TS

There is additional GP data for 564 of the ~16,800 analyst satellites tracked by 18 SDS (USSF). There is also SupGP data for 12,646 active satellites. 12,646 have GP data (76.4%) and another 0 are for active satellites that have been lost (despite having SupGP data*) or are yet to be cataloged. There are 23 gaps in the SATCAT which may be associated with recently launched objects that have yet to be catalogued. Additional information can be found in the SATCAT Boxscore and the SATCAT Growth chart, as well as the Launch Boxscore.
