[edit ]PZ-90.02
[edit ]Creation date - 2005; Epoch - 2002.0; Absolute positional accuracy - from 0.3 to 0.5 m; Relative positional accuracy - from 2 to 3 cm [2]
PZ-90.11
[edit ]Creation date - 2011; Epoch - 2010.0; Absolute positional accuracy - 5 cm; Relative positional accuracy - from 0.5 to 1 cm [2]
PZ-90.11 is described as "closest to ITRF2000" by the ESA's Navipedia. It converts to ITRF2008 with only a shift vector; no rotation or scaling is needed.[3]
