CORE TECHNOLOGY
                     

20cm (7.9 in.) - Ultra-Short Minimum Focus The AT-B Series can focus on objects at 20cm (7.9 in.) in front of the telescope. This feature dramatically facilitates the works in confined spaces.

All-Weather Dependability With the IPX6 rating, the instrument is protected against powerful water jets from all directions, meaning the AT-B Series withstands a sudden shower or torrential rainfall. The advanced protection design also deters clouding or condensation inside the telescope

A: The difference between the rover station and the base station is that the accessories are different, the function and hardware configuration are the same.You can use the controller to choose the working mode of the device and set it as the base station or rover station.

Q: What is CORS?
A: CORS is called a continuous operating reference station system. It can be understood as a bas e station that is erected at a fixed known point and works continuously for 24 hours and sends its own data to a specific serverthrough the network. The use of CORS operation eliminates the need for a base station, and CORS is equivalent to a base station in a normal network operation.
