Abstract The algorithm for detecting whether an equipment terminal with satellite positioning is within the set range or not deserves attention, which is the decisive factor in the design of an electronic fence. An algorithm for entry fence detection based on support vector machine using classification method was proposed. The algorithm mainly consists of three parts: selecting an appropriate kernel function according to the location data of the satellite positioning terminal; calculating the values of kernel function and error penalty parameters through grid searching technique; adjusting threshold value until the detection accuracy is highest. The validity of the algorithm was demonstrated using experimental data from satellite positioning terminals. The detection accuracy rate is estimated to be 80%～96%, which is much higher than the accuracy of 43%～67% obtained by direct detection. The result embodied high practical value for the society.
