Can gates detect where an incoming wormhole comes from?

[Zalenka]

In Atlantis the gate was programmed so that the gate would only be able to accept travellers from Earth. Do you think this is a feature all the gates share or is it just the gate in Atlantis?

If all the gates could do this though we could use it to develop secret bases. Any ideas?

Well you can monitor the incoming wormhole, and probably even the strength of the wormholes energy signature. If an extra galactic wormhole requires more energy to create it, that would be detectable on the far end. Therefore any long distance gate address can then be used to lower the shields. Given the fact that the only address for atlantis was in the antarctic outpost there aren't a lot of others who would be dialing the address. Let alone have the ability.

Just like a high power radio transmission has a different yet similar pattern to a low powered radio transmission.

no you can't, normally with a DHD. NOw if you built your own you might be able reconfigure it

So does the gate in Atlantis, whose DHD is attached to the computer core, possess that ability; while others do not?

So it has a more sophisticated control system?

technically it was programmed to only accept an 8th chevron adress, not just earths adress.

they probably could use the energy signature of the incomming wormhole but they would need to have the pattern first so they could only use it for known addresses.

here's a thought: the wormholes operate thru subspace right? atlantis has supspace sensors, so could they use the sensors to determine which direction the wormhole is comming from?

Short answer...yes, they detect which gate is dialing in, there just isn't a display screen to tell the person standing at the DHD.

how do u no that. i thought they were only designed to pick up drifting objects(ships, asuran satillite weapons, etc.)

give rodney 5 minutes with the DHD and his pad PC.

The gates can detect other gates(not talking about Atlantis's sensors) and determine who is dialing in. It was stated to alternate Weir that the Ancients locked out all addresses except Earth from dialing in, therefore the gate would have to know who to block and who not to, which means they have 'caller id.'

Atlantis' DHD was different from any other we've seen, though. It's possible the ability to detect incoming travelers is unique to Atlantis.

if atlantises computer system can handle it then it stands to reason that we can back-engineer a similer sytem for the earth gate

also in 48 Hours mckay said that the SGC computers ignored 200 of the 400-something signals coming from the gate. it stands to reason here too that the gates only need to have a display and a computer with the right software.
