emitter's properties on a movable actor

hi guys
i have this question for you.

prevent an emitter from creating a trail of particles. this emitter has to shoot its particles only higher than the actor on which he is, who is a moving actor. Is it possible to make such a smart emitter?

May be my english is not good, i will try with a video:

the particles born on the actor must continue to remain on the actor (same Z axis) in this video create a trail. It can be done?
