With a LCD screen
When you see the smart GNSS receiver i80, you will find there is a screen.
From the screen, we can do the basic configuration to the receiver, and it offers us a shortcut to check the info and status of receiver, without using a controller. This brings conveniences (operate simply and shortly).
There is no need to configurate the base in advance and then take the rover to the survey points. It saves us the battery power and does more jobs.
Also, you will find more from LCD screen when you have one i80 in hand.
