Israeli AEW systems.

Ok I have been trying to do some research about the AEW systems offered by Israel and frankly I have not got very far.

Does anybody know the relationship between the original condor system (as sold to chile) the system being fitted to the Il-76 for India and what seems to be the most technologically advanced variant fitted to the IASF G-550 (EL/W-2085) According to AFM Elta claims this system (G-550) to be better than the wedgetail, so is the IAF’s version a scaled up version of the G-550 version or is the G-550 version the latest evolution? And which is the most capable (in terms of radar and software performance- not platform performance)?
