【摘要】 GPS多天线技术,旨在降低GPS在大坝等形变监测等方面的应用成本。文中研究的多天线系统,使得一个GPS接收机可以联接多个天线,从而实现一机对多点的监测。实验表明,该系统对GPS信号的衰减、GPS测量精度几乎没有影响。更多还原

【Abstract】 GPS multi-antenna technology is researched to reduce the cost of GPS when used for monitoring of deformations of objects such as slopes. The multi-antenna system (GMS) described in this paper allows many antennas to connect to one receiver,which can monitor many points. Test results show that GMS has almost no influence upon GPS SNR and measuring accuracy.更多还原
