The Best-in-Class GNSS Engine
The integrated advanced 1598-channel GNSS technology helps K7 to collect signal from GPS, Glonass, Beidou, Galileo, QZSS, in particular the latest BeiDou III. It greatly improved the data quality and satellite signal capturing speed of GNSS surveying.
New Radio, Farlink Tech.
Farlink technology is developed to send large number of data and avoid data loss.
This new protocol improves the signal-catching sensitivity from -110db to -117db, so K7 can transmit to 10 km away by only 1 watt power consumption.
kFill, Save RTK Correction Signal Loss
Kolida's kFill technology is able to provide a 5-minutes sustainable high accuracy service during a temporary RTK or VRS signal coverage outtages. After the correction data signal recovers, receiver will switch to real time correction data connnection seamlessly.
