* Specifications will vary depending on the number of satellites used, obstructions, satellite geometry (PDOP), multipath effects, and atmospheric conditions. For maximum system accuracy, always follow best practices for GNSS data collection. 1 ppm means 1 mm/km away from base. ppm is limited to baselines up to 20 km.
