GCAT Release 1.8.8 (2026 Sep 3) | Data Update 2026 Sep 3
Active Catalog Column Descriptions
The
active catalog
lists payloads which are or may be still transmitting.
However, I only infrequently update the active/not-active status of satellites and in any case the status is often a guess,
if the satellite does not actively manuever.
The fields in this file are all simply copied from satcat and psatcat, for full explanation see the documentation
for those files.
