All,

Using detailed doppler shift measurements, I find that PSAT is object 90720, ULTRASat 1, and BRICSat is object 90729, ULTRASat 10.

Up-to-date TLE sets for these satellites can be found here: http://mstl.atl.calpoly.edu/~ops/ultrasat/ultrasat_jspoc.txt http://mstl.atl.calpoly.edu/~ops/keps/kepler.txt https://docs.google.com/document/d/1o48dswYcTHb-op9ygaKhrizrelMGV9pYcUm0SFmx...

This means that PSAT is actually object 40652, 2015-025B, and BRICSat is actually object 40661, 2015-025L, in the JSpOC catalog. But Space-Track does not publish TLE sets for these objects.

Meanwhile, The Planetary Society suggests that the TLE set for object 90721, ULTRASat 2, gives the best match for LightSail. If that is correct, then LightSail is actually object 40653, 2015-025C, in the JSpOC catalog.
