(2) BE-GPS-6500 - Bad Elf Flex Extreme GNSS Receivers
(2) BE-URK-5000 - UHF Flex Radio Kits
A full Base / Rover Solution
(Rover Rod Poles Sold Separately)
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
