Why Do my Devices Show in different Location on the Site Management App than on the ground?

When hardware is deployed using the Dryad Deployment App the app relies on your phone's GPS to pinpoint the device's location. In some cases, devices can appear slightly off (5m radius) their exact Geo Location. If your phone has good 4g-5g connectivity, it will use mobile data to calculate the position, resulting in more accurate outcomes. If there is no connectivity, it will use internal GPS and is often less precise. 

You can increase accuracy by enabled accuracy settings in your smartphone.

eg. for iOS: Settings > Silvanet > location > enable "Precise Location"
