A vehicle-mounted satellite positioning system speed delay interval period number measuring method comprises the steps that whether a locomotive is in a variable-speed motion state or not is judged by obtaining the acceleration change rate and positioning state information of the locomotive at the current moment; if not, information obtained through radar speed measurement, satellite positioning speed measurement and locomotive wheelset speed measurement after locomotive variable motion is collected, satellite positioning data transmission time, namely delay interval period number optimization calculation is carried out, and accurate real-time satellite positioning data transmission delay time, namely the delay interval period number, is obtained. According to the method, the accuracy and the reliability of calculating the speed data of the electric locomotive are ensured.
