What Happens in SurvCE’s Raw File
When You Configure a GNSS Base

The following discussion explains what is going on for when you setup a base in SurvCE, what gets loaded in the
receiver and what entries are made in the .CRD, .REF and .RW5 files:

.CRD

Job ‘Card’ file. May also have a .CRDB extension (new style)

.REF

Base Reference file

Information you may need when looking at this discussion and example:

When you setup a base, the HI is entered on the Receiver tab.

In this example the base is on a fixed height 2-meter rod so the Antenna Height is:

2.0000 m = 6.5617 sFeet

Vertical distance from GM to ARP

After configuring the ‘RTK’ tab, and then doing a 10 point average, this is the ‘Base Configuration’ screen:
