AGTEK Development Company, part of Hexagon, has released the SmartDirt RTK, which turns Apple or Android phones or tablets into high accuracy GPS/GNSS receivers for on-site grade checking, drone/UAV ground control point (GCP) set out, and site data collection. SmartDirt RTK supports both Apple and Android devices when paired with a compatible RTK antenna.
SmartDirt RTK allows users to know where they are in relation to plan sheets, cut/fill maps, satellite images and street maps, leveraging the power of mobile devices. The app can determine the volume of a stockpile, find the daylight line between cut and fill, and calculate balanced regions in the field to ensure dirt only moves once. SmartDirt RTK also records site details with RTK accuracy and uses the camera on mobile devices to record site progress.
SmartDirt RTK transforms the GPS in mobile devices from accuracies of within several feet to accuracies within a tenth of a foot for survey-grade measurements. When the RTK antenna is connected to a reference network, there is no need for a base station as the position is calculated directly in state plane coordinates.
