| 摘 要： | 针对常规GPS应用中成本较高的问题，文中研究了GPS多天线数据采集与控制系统，实现了一机对多点的监测。实验和实际应用表明，该系统对GPS信号的衰减，GPS测量精度几乎没有影响。该技术使得GPS监测局部区域人工和自然结构形变（如大坝，建筑等）的监测费用大大降低，具有重要的实用价值。 |

| Abstract: | 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. |
