Is there an old 'PSAT' ?

AMSAT has never listed any other spacecraft as PSAT.

In general, the TLE's in nasabare.txt are the best available and are updated as significantly better element sets present themselves. In the last week I have been using elements provided by USNA and the Planetary Society as appropriate for PSAT, BRICsat and Lightsail. Once NORAD has sorted out all the objects from this launch, they will be updated weekly with the other objects in nasabare.txt

ISS continues to be updated at least daily with data from NASA Johnson space flight center.
