New Model Kolida K9 Mini Smart Rtk GPS Receiver
Equipped with the most advanced GNSS positioning technology, K9 Mini will provide you an awesome working experience.
Featuring an ultra-powerful GNSS mainboard, K9 Mini can track and process signals from GPS, GLONASS, BEIDOU, GALIEO and SBAS systems.
With this superior multi-constellation compatibility, the satellite availability,signal acquiring speed are greatly improved, the waiting time has been shortened and the positioning accuracy (RTK) is up to 8mm+ 1ppm in horizontal and 15mm+ 1PPM in vertical.

220 channels, Pacific Crest GNSS Motherboard, support GPS/GLONASS/Galileo/BeiDou
Built-in GPRS (3G optional) modem and UHF data link
Interchangeable between base and rover mode
Small, lightweight and rugged design for demanding environment field work
