Updated PY4 TLEs below for those that are interested. Generated from on-board GPS.

As it stands, the TLEs in SatNOGS DB are all correct except for PY4-3, which should be updated to Object AZ (which is currently identified as MH-1). Time will tell whether or not Object AZ is a PY4 bird or MH-1, but for now our GPS solutions are a strongest match for that object.

To summarize the current PY4 object guesses:

PY4-1 = Object AS 
PY4-2 = Object AT
PY4-3 = Object AZ
PY4-4 = Object AY

The custom TLEs for those that are interested:

PY4-3 is listed under NORAD 59145, however this ID is assigned a sat MH-1 in space-track.org. In fact the correct ID seems to be 59143 (OBJECT-AX). Pls check.

This was done on purpose following this suggestion.

@maholli any opinion for 59143 (OBJECT-AX)? Does it match GPS data from PY4-3?

@fredy @stefanp

It’s always possible we could be wrong, but as of our last analysis on March 25, OBJECT-AX was no where close to being a PY4 candidate, whereas OBJECT AZ (MH-1) had a consistent sub 10-meter fit.

I’ll have time to do another comparison early next week and report back with our findings.
