URGENT MESSAGE: From TS Kelso of CelesTrak "[The US Space Force 18th Space Defense Squadron] will run out of 5-digit catalog numbers at 69999 not 99999, which is estimated to occur around 2026â07â20 (we're currently at 68014). At that point, 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 this limitation (and finally fixed the Y2K problem) in May 2020 and immediately began providing GP data in those formats for software developers. The same limitations apply to the legacy fixed-field SATCAT. Follow @TSKelso on Bluesky for the latest updates, tutorials, and changes as we approach this transition. Spread the word!"
AMSAT is presently alpha testing dissemination of orbital data aka "General Perturbations Data" or "GP Data" in formats that do not have the 5 digit object number limitation and will solicit public help for beta testing in April 2026. Many software packages used by hams already accept at least one of the new formats, and we would like to work through any issues before new satellites arrive without TLE sets. AMSAT will continue to disseminate TLE data for all satellites cataloged below 69999 indefinitely.
NOAA Cat ID 67291 has been renamed "RS95S (QMR-KWT-2)"
