I have set up a system for surveying points with a Juniper Geode GPSS because the survey team is too busy to do it themselves. There is a consistent shift to the northeast of the coordinates I am surveying with the GPSS vs what the surveyors got with their Trimble RTK system. The coordinates have good precision but a consistent problem with accuracy.
I am using an app called MapIt on Android to collect the coordinates. The coordinate system is NAD83 in UTM.
Is there a way to eliminate this consistent northeast shift? Is there a way to post process the data easily, or is there a coordinate system problem? I am not a surveyor so I've had trouble even setting the GPS up.
