PROBLEM TO BE SOLVED: To obtain positioning results from a plurality of observation stations with required accuracy while reducing a load on data processing and data transmission in a short time.SOLUTION: A displacement monitoring system includes: a reference station 10 for receiving a signal for positioning broadcast from each satellite; an observation station 20 installed in a monitoring object range for receiving the signal for positioning periodically broadcast from each satellite; and a monitoring part 3 for monitoring the position displacement of the observation station 20. The reference station includes reference side communication parts 1102 and 113 for transmitting the signal for positioning received by an own station to the observation station. The observation station includes: positioning arithmetic means 2102 for, from the signal for positioning received by an own station and the signal for positioning of the reference station received by the reference station, obtaining the positioning result of the own station by kinematic baseline analysis; and observation side communication part 2104 and 213 for receiving the signal for positioning of the reference station, and for transmitting the positioning result of the own station to the monitoring part.SELECTED DRAWING: Figure 2 【課題】短時間でかつデータ処理及びデータ伝送に対する負担を軽減しつつ所要の精度で複数の観測局からの測位結果を得る。【解決手段】変位監視システムは、各衛星から放送される測位用信号を受信する基準局１０と、監視対象範囲内に設置され、衛星から周期的に放送される測位用信号を受信する観測局２０と、観測局２０の位置変位を監視する監視部３とを備える。基準局は、自局で受信した測位用信号を観測局に送信する基準側通信部１１０２，１１３を含む。観測局は、自局で受信した測位用信号及び基準局で受信した基準局の測位用信号から、キネマティック基線解析によって自局の測位結果を求める測位演算手段２１０２と、基準局の測位用信号を受信すると共に、自局の測位結果を監視部に送信する観測側通信部２１０４，２１３とを含む。【選択図】図２
