Heavy duty satellite tracking turntable
The direct drive dual axis tracking turntable has two degrees of freedom in azimuth and elevation, and is a TL 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 and laser communication satellites, and together with the satellite transmitter, it can complete satellite ground quantum communication and laser communication. Cooperating with the customer's software control and navigation design, the turntable has the ability to track low orbit satellites.
