Abstract:

Detailed SW assembly of ALIGO IO PSL ISS PD ASSEMBLY.
_________________________________________________________
Status of all units ever made as I understand them from various doc hints at the moment (May 2024) - BW:
S1202965 - at LHO, Labeled in pen "ready for installation" - in lab now, updating with some of the smaller upgrades and then will be the working spare (maybe swap at LHO Post O4)
S1202966 - at LHO, Was removed from LHAM2 2016, replaced with S1202969 - Open next at LHO to see how it looks/characterize
S1202967 - at LHO, T1300063 hints at parts used for another ISS during the 2016 trip to and from LLO - "contam and damage" in lab Mar 2025
S1202968 - at LHO MY for 3IFO
S1202969 - at LLO in HAM2
S1202970 - at AEI ?
S1202971 - at LHO in HAM2
S1202972 - at AEI ?
S1202973 - An incomplete dirty assembly Found at LHO.
