A Temporal synchronization beacon, or TSB, is a vital component of Lodestar satellites used to standardize time for all major Terran factions in the Koprulu Sector.
Due to every planet have its own orbit and time zones, TSBs rectify most relativity related problems experienced by ships entering one system to the next. This is especially important in organizing movements of military fleets and civilian flotillas. Any miscalculation can mean the difference between losing a cargo ship to ramming a Battlecruiser, so tampering with a beacon is a serious offense to all three major governments.
