摘　　要：介绍了Gquicks软件的数学模型,Gquicks软件的结构和功能。经实测检验,当基准点与监测点之间距离在3km内,用20分钟GPS观测值,Gquicks软件解算的水平精度可达±2-3mm,垂直精度可达±4-6mm。Gquicks软件不仅适用于GPS滑坡变形监测,也可应用于其他变形监测领域。In the paper,an introduction to mathematical model of the Gquicks software is presented with its configuration and its functions. Through measurement checkout, the monitoring distanceCdis-tance between base point and monitoring point) is less than 3 km,the level precision reaches±2-3mm and the vertical precision reaches±4-6mm by GPS phase observations 20minutes. The Gquicks software is not only used for the landslides monitoring but is also used in some other monitoring applications by GPS.
