There are mainly three methods to enter the reference coordinates and shown as follows:
a) Acquire Current Position: Click this button to acquire current position obtained
through autonomous positioning automatically.
b) Manual Input: Manually input the coordinate of a control point.
c) From CORS: After the receiver logging in CORS, the software can record the coordinate
of current position based on fix solution.
For Sample for Average:
Users can determine the positioning limit and sampling amount. The positioning limit falls into
two types:
a) Single Solution Coordinates: Collect the coordinates of receiver obtained through
autonomous positioning.
b) Fixed Solution Coordinates: Only collect coordinates of receiver with a fixed solution.
After the configuration of positioning limit and sampling amount, click to carry out
sampling and averaging → the progress bar will show the progress → the result will be served
as the coordinate of current position.
If users need to save the changes, please tap button.
