Repeat Position: is used to input a permanent base station position
into the S321. You may type in a latitude, longitude, and altitude, or
click “Current Position” to automatically populate the field with the
current GNSS position.
BaseLink: (Upcoming feature) this feature requires an Atlas H10 (10‐
centimeter) subscription. Input a Target Accuracy. Once the accuracy
of the GNSS position of the receiver has reached the Target Accuracy,
the receiver will begin to output RTK based on its calculated position.
The accuracy of the GNSS position may continue to improve. If it does
improve, a new target accuracy may be entered, and the base position
will shift to reflect the new accuracy.
