Empire1guy, what your probably referring to is the South Satellite (Pima) sector. That sector gives aircraft practice approaches, flight following, and all IFR aircraft out of CHD and IWA etc. That sector operates from the P50 TRACON (along with all the other approach/departure sectors). Let me know if you have any more questions.
