Signal GK

Abbreviation for Gashimeku Kaalariin, Vilani for vessel in distress. The code signal GK originated on Vland as a distress signal in maritime and aviation activity, and was one of the standard communications codes of the Vilani Imperium. When the Second Imperium succeeded it, signal GK was retained as a distress code co-equal with the Terran SOS and Mayday signals.

The Imperial Navigation Act of 103 requires all vessels, whether military or civilian, to respond to the GK, SOS, or Mayday signals, provided such response does not endanger the ship and crew of the responding vessel.
