Skaro Control
From Tardis Wiki, the free Doctor Who reference
The crew of the first Dalek time machine, after taking off from Skaro, maintained contact with Skaro Control as they pursued the First Doctor through time and space. Upon their arrival on Mechanus, Skaro reported that the Mechonoids possessed powerful weapons. (TV: The Chase, PROSE: The Chase) The destruction of the time machine was noted on Skaro.
