Abstract: 針對常規 GPS應用中成本較高的問題 ,文中研究了 GPS多天線數據采集與控制系統 ,實現了一機對多點的監測。實驗和實際應用表明 ,該系統對 GPS信號的衰減、GPS測量精度幾乎沒有影響。該技術使得 GPS監測局部區域人工和自然結構形變 (如大壩、建筑等 )的監測費用大大降低 ,具有重要的實用價值。
GPS is proved to be a useful tool for monitoring deformations of dams, bridges and slopes. In the standard method for using GPS in deformation monitoring, one GPS receiver must be equipped for every point to be monitored. Wide application of GPS for civil use is restricted by the high cost of receivers. GPS multi-antenna data acquisition and control system (GMS) can make one receiver connect with several antennas. That is, with this system, one GPS receiver can be used to monitor several points. All tests show that GMS has almost no influence on the signal and measuring accuracy of GPS. By using this technology, the cost of GPS used for local monitoring deformations of many man-made or natural structures, such as dams, slopes and volcanoes, is significantly reduced.
