2DT400GZ 2D tracking turntable
The 2DT400GZ two-dimensional tracking turntable has two degrees of freedom of motion, the azimuth axis and the elevation axis, and is a UT type two-dimensional tracking device. A device that simulates satellite pointing and attitude on the ground while eliminating the influence of Earth's rotation. It can be used as a ground receiving station for quantum communication, together with a quantum satellite transmitter, to complete satellite ground quantum communication.
In conjunction with user software control and navigation design, this two-dimensional tracking turntable has the ability to track satellites
