2-STGZ/1 Direct Drive Dual-axis Tracking Turntable
Product Description
2-STGZ/1 direct-drive dual-axis tracking turntable has two degrees of freedom of movement in the azimuth axis and pitch axis. It is a TL-type two-dimensional tracking equipment. A device that simulates satellite pointing and attitude on the ground while eliminating the influence of the earth's rotation. It can be used as a quantum communication ground receiving station, and together with the quantum satellite transmitter, it can complete satellite-to-ground quantum communication. Cooperating with the user's software control and guide design, the two-dimensional tracking turntable has the ability to track satellites.
1. Adopting L-shaped structure, it has great flexibility in load installation;
2. The use of high-precision encoders ensures high reliability of tracking accuracy;
3. DC motors and drives reduce transmission links and ensure that the system has no transmission errors;
4. The main structure of the equipment is made of aviation cast aluminum alloy material, which is light and stable.
