GPS antenna array deformation monitor

The utility model relates to a GPS antenna array deformation monitor which is formed by connecting a GPS receiver with GPS antennas and a control unit MCU, wherein a multi-way microwave switch is arranged among the GPS receiver and the GPS antennas; each GPS antenna has a single power supply circuit, and is characterized in that each way of the microwave switch and a switching control end of each single power supply circuit are connected with control signals sent by the control unit MCU; in the control unit MCU, a microprocessor is also connected with a network interface circuit. The utility model utilizes one GPS receiver to carry out the deformation monitoring of multiple deformation points and reduce the equipment cost. The utility model nicely solves the problem of mutual interference among multiple paths of GPS antenna signals; the means of data transmission are perfect; various modes can be supplied to be selected, and the distance of data transmission can be increased.
