摘　　要：GPS技术在公共安全监测领域中的应用正向高精度、实时化和自动化的方向发展。GPS公共安全监测不仅注重结果,还要分析产生变形的原因。要实现这一目标,就需要借助于G IS的空间分析功能,即需要建立一种基于GPS/G IS的公共安全监测系统。研究了GPS监测的似单差数学模型和算法流程,由于该模型只用到L1载波相位观测值及伪距,因此可适用于单频接收机,从而降低监测成本。同时,结合GPS公共安全监测的特点,提出了GPS/G IS公共安全监测系统的技术路线。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.
