Reference Station Coordinate System

What Coordinate System is the Reference Station using.
I am following these instructions, but configuring for your unit instead.

Using WKID 8999, I am about 3 ft off from a previously surveyed point.

Thanks,

WGS84 by default “The SparkFun RTK product line outputs coordinates in the WGS84 coordinate system by default and can output ECEF as well”

Be sure to also input your ARP offsets (if applicable)

iOS - SparkFun RTK Product Manual Here is some general ios info as well in case it helps

The provided instructions state “In the United States for example, RTK corrections are usually broadcast in reference to the NAD 83 (2011) datum”.
The RTK result will be in the same coordinate system NAD 83 (2011).

The Public Reference Station is using NAD 83 (2011).

Typically the RTK result for public base stations will be in the same coordinate system as the station coordinates given.

If the RTK result is to be presented on a map, it must be transformed (projected) from a 3D system to a 2D system. Some additional receivers software can do this automatically after setting the transformation in the configuration. If this is not possible, you can do it using the PROJ program.

It is not true that RTK produces results in WGS84 by default.
