The most common reason for your GNSS locations not to be aligned with your map data is due to a datum incompatibility. In other words, your GNSS coordinates are in a different datum than your map datum.
If you are using RTK corrections, then a datum transformation of GNSS coordinates coming from your Arrow receiver might be needed. Coordinates output by the receiver will be in the same reference frame or datum as the differential correction source. For example, most RTK networks in the United States are referenced to the NAD83 2011 datum. If you’re not sure what datum your RTK corrections service is referenced to, ask your RTK provider.
Once you know which datum your RTK corrections are using, you need to ensure your datum transformation is properly set in your GIS app.
If you are using ArcGIS® Field Maps, the way you do this is to have the proper location profile configured — according to your RTK datum and your desired ArcGIS map datum — in the app. To learn how to set an RTK location profile in ArcGIS Field Maps, click here and follow the steps.
