The invention discloses a position acquisition method and system based on Tiantong satellite short messages, and relates to the technical field of communication. In the system, a position acquisitionsystem comprises a Tiantong terminal and a position management center, and the Tiantong terminal comprises a main control module, a Tiantong baseband module and a power supply module. The position management center comprises a GSM modem device and a server. According to the invention, the position management center and the Tiantong terminal carry the position acquisition signaling on the short message for interaction, thereby realizing acquisition and control of the position information of the Tiantong terminal by the position management center. According to the method, the coding characteristics of the short messages are fully considered, and a simplified position acquisition signaling interaction process and a system implementation scheme are designed. 本发明公开了一种基于天通卫星短信的位置采集方法及系统，涉及通信技术领域。该系统中，位置采集系统包括天通终端和位置管理中心
