When a network of reference stations with nationwide coverage, VRS gives 2 versions of Fixed solutions (5min reps) with the same 18cm vector difference, only in a certain area of coverage ,
the cause could be the poor coordinates of one of the stations used by VRS and depending on which one it has as its central one, it gives the corresponding results ?
Has anyone encountered something similar only in a certain place? Sorry for my google translate English
Getting different results in a certain area between VRS and RTK does not mean that there is a problem with a reference station. Check your satellite map on the DC (take a photo when connected to VRS and RTK) and see if you are missing any key satellites.
