The invention relates to a smart phone based satellite push-to-talk communication terminal control system. The smart phone based satellite push-to-talk communication terminal control system comprisesan upper computer system and a lower computer system; the upper computer system comprises a smart phone; the lower computer system comprises an antenna feeder and servo control sub-system, a radio frequency sub-system, a communication sub-system, a power supply sub-system and a single-chip machine. The invention also relates to a smart phone based satellite push-to-talk communication control method; a control algorithm is finished by the smart phone, so that configuration demands for a servo control single-chip machine are reduced greatly. The smart phone based satellite push-to-talk communication terminal system realizes all or partial functions of four sub-systems, including an antenna gesture measurement sub-system, a communication sub-system, a radio frequency sub-system and an ACU sub-system in the prior art by using application programs of one smart phone. Space occupation of the system and costs are reduced greatly, and reliability also can be improved remarkably.
