You can configure a Mobile app that is capable of connecting to a high-precision GNSS receiver in order to gather very accurate location field data. From within the Mobile app, you can switch quickly from your integrated device GPS to a connected GNSS receiver, and see details about the horizontal and vertical accuracy, satellites in use, etc. You can set the antenna height if it is required, and then select the Datum Transformation to use. The Datum Transformations listed for you to select, will all function with the GNSS receiver and the web map that you are using.
