Ground Control Points (GCP)

This is Venkat, We Have Esurvey GNSS & Emlid Reach RS2, both machines run are different date’s on Same position and both as 3Hrs Running but the Output points value are miss matching can any on Explains this issue…

Your heights are significantly different. Did you use the same antenna height for both? I would assume different Antenna Reference Point (ARP) for each.


Hi Venkat,

Welcome to our community!

Could you please elaborate on how the coordinates were calculated and which solution status was obtained in each case (Fix, Float, or Single)? It will help me to understand the issue better.
