摘要
研究了区域变形监测的多天线 GPS系统。该系统特别设置了一个电子元件 ,可将多个 GPS天线与一台GPS接收机相连 ,接收机依次从每个天线获取数据。本系统的优点 ,是使用一台 GPS接收机监测多个变形点 ,极大地节省了变形监测的费用。本文详细地介绍系统的设计原理以及数据管理和数据处理方法 ,并给出系统的试验结果。
A multi antenna GPS based system developed for local area deformation monitoring has been presented. The system uses a specially designed electronic component that allows a number of GPS antennas to be linked to one GPS receiver. The receiver takes data sequentially from each of the antennas attached to the receiver. A distinctive advantage of the approach is that one GPS receiver can be used to monitor more than one point. The cost per monitored point is therefore significantly reduced .The design of the system, as well as the data management and processing strategies are introduced in detail. Results from the tests of the system are also given.
