 ===== Transponders =====
-All civilian vessels continuously broadcast a transponder signal.
+All civilian vessels continuously broadcast a transponder signal. It can generally be picked up within 30Mkm with civilian sensors, or 100Mkm with military grade sensors.
+Military ships will often switch off their transponders when on a mission, though it is against Imperium law for civilian ships to do so.
+The transponder signal carries the ID of the ship, and where it was registered, and has enough information to work out the heading of the vessel.
+===== Starports =====
+Starports will generally have high quality sensor arrays that allow them to monitor most of the star system.
+They have neutrino sensors which allow them to detect a ship's jump (either out, or in).
+The general ranges at which a starport will be aware of what's going on depends on its size. Double these ranges if there is a Naval base present.
+==== A ====
+  * Transponder signals with 30 AU.
+  * Detect jumps within 10 AU.
+==== B ====
+  * Transponder signals with 10 AU.
+  * Detect jumps with 3 AU.
+==== C ====
+  * Transponder signals with 3 AU.
+  * Detect jumps within 1 AU.
+==== D ====
+  * Transponder signals with 1 AU.
+Increase by one range band if population is 1 billion+. Increase by 1 range band if TL is 13+.
+Range bands beyond 30 AU are 60 AU, 100 AU.
