The technology of GPS applied in public security monitoring is developing toward the high precision,real time and roboticized way with the attention paid to the result and the cause of deformation.In order to reach the goal,it needs to set up the system of public security monitoring based on GPS/GIS space analysis with GIS.The similar single difference model and algorithm flow are studied.Due to the L_(1)carrier wave and pseudorange,which is suitable for single frequency receiver,the monitoring cost is reduced.At the same time,the technology for system of public security monitoring based on GPS/GIS is put forward according to the characteristics of the public security monitoring.
