There is no specific mention of Galder Starkiller in any of the transmissions you crack into. But as you trawl through the navcomp and the ship logs, you get two things.
You cannot find a trend with anywhere the starship has been. It has not visited the same place more than once. However, the navcomp is fixed to a faint beacon.
Also, any transmissions made by the transport were either to the two starfighters accompanying or to something known as 'Guidance.' All records were wiped prior to its venture to Magnus.
