Aiming at the problem that the single-frequency augmentation message broadcasted by the satellite-based augmentation system (SBAS) is generally used to enhance the single-frequency positioning, the paper proposed a method of using single-frequency augmentation message to enhance dual-frequency positioning, and derived the mathematical models of using the single-frequency augmentation information to enhance the single-frequency and dual-frequency standard point positioning (SPP) , and furtherly analyzed the enhanced performances of the BeiDou satellite based augmentation system (BDSBAS) and the wide area augmentation system (WAAS) .Results showed that when using BDSBAS and WAAS single-frequency augmentation information to enhance SPP, the three-dimensional accuracy of global positioning system (GPS) L1C/A single-frequency positioning would be improved by 25％～50％ and 45％～70％ respectively, and the three-dimensional accuracy of GPS L1C/A + L2P dual-frequency positioning would be improved by 10％～40％ and 10％～50％ respectively.
