Hello We are working on a pipeline project and setting out centerline bu using Leica GS15 devices with RTK. When we install base station, base instrument does not accept the given base station coordinates. When we install the base station without giving any coordinates, it gives around 1 m difference with given base station coordinates. I mean the base instrument does not correct the measured data. I am new at gps devices. Does anybody knows what we are doing wrong. Thanks
