The invention discloses a smart phone terminal with built-in Beidou short message and Beidou positioning functions. The terminal comprises a smart phone platform, a Beidou short message module, a Beidou positioning module, a master central processing unit (CPU) and a lithium battery, wherein the smart phone platform, the Beidou short message module and the Beidou positioning module are connected with the master CPU through serial ports. Based on conventional smart phones, the smart phone terminal is added with the Beidou short message module and the Beidou positioning module. Due to integration of the Beidou short message module, besides common voice and communication functions of the conventional smart phones, the smart phone also allows users to send satellite short messages through the Beidou satellite. As an important emergency communication supplementary means, the Beidou satellite short message communication is convenient for outdoor workers to perform emergency communication.
