BASE/ROVER REIMAGINED 
  • 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.
ACCURATE
  • Built on the survey-grade Hemisphere Phantom GNSS engine
  • Expected accuracy - 1 cm horizontal in good conditions
  • Quad-constellation corrections source from base to rover
  • Range (power-determined) 2-10 km line-of-sight
  • Global operations, regardless of cellular coverage
AFFORDABLE
  • A professional system for a cost-competitive price without sacrificing features or functions
VERSATILE
  • No need for dedicated devices and configurations. 
  • Bad Elf Flex Extreme operates as either a base or a rover. (Rover mode is available with Flex Standard using a Flex Token to enable Extreme mode)
  • Simply fire up the Flex app and enable either mode of operation.
