How to use RTK express

hello.

I’d like to ask you questions while using RTK after watching “RTK Express Hookup Guide”.

  1. What does “Mean” mean in the survey procedure at Base Station?

As a result of the test, if 30 satellites are used and move on to the survey procedure, “Mean” will be lowered to 0.7. (If “Time” is set to 600 seconds via S/W)

  1. We are communicating base and rover through 915 MHz communication, but why is it because it is disconnected in the following cases?

-. Base setting: “configuration base → Set required Mean 3D standard development : 1 meter”

-. Rover Settings: Configuration Base → Set required Mean 3D Standard Deviation : 5 meters"

When I set Base and Rover to “5 meters” because I couldn’t communicate, it became 915Mhz communication. I wonder if it’s because it’s programmed on S/W or if it’s an error.

(Tested in a place without radio interference.)
