Talk:Relay Monument

Orientation of mass relays
According to the codex, the Presidium is rotating. Since the relay monument is fixed in the Presidium, the monument must be rotating with the Presidium.

This present an interesting problem for the mass relay that it is an end point of. Judging from the relay design and cut scenes, relays work in a direction. The sending relay propels the payload along a "linear" corridor towards the receiving relay. (Are there codex entries about this?) It appears that for the relay to work, the receiving relay must be at the end of the corridor when the payload arrives. In addition, it looks like it must be aligned with the corridor.

Because the Presidium relay rotates, the transport of the payload must be properly timed, otherwise the relay endpoint would not be properly aligned on arrival. One way to achieve this might be to adjust transport velocity such that arrival is delayed until the relay endpoint is oriented as needed.

Because it is fixed to the planet, the sending relay on Ilos is also rotating. This may be a reason why there is only a limited time to use it.

For relays floating in space, this problem does not exist, since they can be rotated as needed.
