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. Video : https://www.youtube.com/watch?v=BIEyktshIgk

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 2 watt power consumption. (Farlink Pro protocol has been added to K7 since June 2024, working range and stability have been improved.)

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.

Down to 4-10 cm

Positioning by L-band Thanks to the newly developed BDS correction service, K7 is able to receive B2b signal via L-band, and perform a single point positioning precisely without base station. It is a great help to surveyors who work in particularly difficult areas. This service is available in 2022 in Asian-Pacific region.
