Another idea if you don't want to use commlinks to have people track you like Jihahna is trying right now... its not perfect but you could have the Force Users use Telepathy (also under the basic Use the Force skill)...
Telepathy: As an Action you can send a telepathic call, single thought or emotion to one creature. Against an unwilling creature you must exceed their Will Defense. The creature must have an Intelligence of 3 or great but does not need to speak or understand your language, but you have to have at least casual knowledge or the being. Make a Charisma (Use the Force) check DC vs. a DC 10 if you can see the creature, DC 15 if the subject is on the same planet as you are. Increase this to DC 20 if in the same system, 25 in in the same region or quadrant of the galaxy and a DC 30 if in a different region or quadrant of the galaxy.
