Bad Elf introduces a base/rover feature built upon the Bad Elf Flex® GNSS receiver. This new base/rover feature brings affordable centimeter-level accuracy to surveyors and geospatial professionals working anywhere in the world. The solution consists of two Flex GNSS receivers and two UHF radios, allowing customers to perform high-accuracy field data collection in areas where traditional RTK corrections or cellular coverage is not available. Existing Flex customers can upgrade to a base/rover solution by adding a Flex radio kit, one for the base and one for the rover.
