As the question states, in the SGA episode: "First Strike" Atlantis moves from Lantea to another planet.

I can accept that McKay could get the Atlantis gate back onto the Stargate grid, but wouldn't that mean that Atlantis would get a new point of origin?

    What indications are there that it didn't get a new point of origin? – HorusKol Dec 10 '13 at 23:02

It is canon that the gate system has an automated update program so while technically the symbol on their gate remained the same it used their new location as the point of orgin

  • ok so unless im getting confused wouldnt the actual address change also? considering that the first 6symbols denote co-ords? – Lou Dec 11 '13 at 1:33

    @Lou Atlantis might have a fixed address just like the Destiny. Both are technically ships and both can be dialed long distance (read: from another galaxy). So they need to be able to cope with changing positions. I'm not sure if it was addressed in the show how that works exactly. But it might just work like our internet. You access a fixed domain which you perceive as an address but it's technically just an alias that can point dynamically to changing IP addresses. – Sebastian_H Dec 11 '13 at 8:28

    This is just plain wrong. The gate does get a new point of origin; stargate.wikia.com/wiki/New_Lantea – Valorum May 8 '14 at 17:45

They did get a new point of origin (PoO)...

The Stargate Wikia lists New Lantea as having a different point of origin symbol to (Old) Lantea.

Lantea PoO symbol;

PoO Symbol Lantea

New Lantea PoO symbol

PoO Symbol New Lantea

We also know that by the point that Atlantis moves, Carter and McCabe are well aware of how to reprogramme a gate and create a new point of origin, as evidenced by their upcoming plan to retask dozens of gates to make a trans-galactic bridge.

  • There is also the way Daniel used the gate on Apohis' ship with Earth's point of origin to access the Alpha Site and escape before they were destroyed - once they knew what the origin point is (and like you said Carter/McKay were in the midst of retasking a whole bunch of them), I doubt that much reprogramming would need to be done – Robotnik May 8 '14 at 7:19

    @Robotnik - Yes, by this point they've got a laptop/DHD interface working. – Valorum May 8 '14 at 17:34
  • Your acronym for "Point of Origin" is incorrect. It should be PoO. – Omegacron Feb 23 '15 at 21:50
  • Once they reach Earth however, maybe this is a new question, would not the same situation as the Russia get begin with Earth being the origin point for both gates? Or would the Atlantian gate be fancy enough to still work with its own? – Odin1806 Aug 31 '17 at 20:47

    @ench - I seem to recall that the Midway station was a safety 'air-gap' rather than because the networks were inherently incompatible. Possibly worthy of its own question though – Valorum Aug 31 '17 at 22:38
