Zusammenfassung:The invention discloses a differential positioning method. The method comprises steps of determining the satellite observation quantity, and obtaining differential data broadcasted by at least two differential service providers; and selecting a target differential service provider from the at least two differential service providers according to the satellite observed quantity and the data qualityparameter of each differential data to execute the positioning operation of the terminal. The invention further discloses a differential positioning device, a terminal and a computer storage medium.The method is advantaged in that the target differential service provider is selected to execute positioning of the terminal through the positioning operation executed by different differential service providers, more accurate differential service providers are provided to complete terminal positioning, and precision of the terminal positioning result is improved. 本申请公开了一种差分定位方法,该方法包括:确定卫星观测量,获取至少2个差分服务商广播的差分数据;根据卫星观测量与各个差
