X-Series Gss Kolida
Farlink Radio Gnss Kolida

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 K7X can transmit to 10 km away by only 1 watt power consumption.

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.

L-Band Gnss Kolida

Thanks to the newly developed BDS correction service, K7X 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


KOLIDA’s 3rd generation inertial sensor and algorithm are onboard now. The working speed and stability have been improved for 30% from the last version. When the GNSS fixed solution is lost and recovered again, Inertial sensor can remain the working status in a few seconds, no need to spend time to reactivate it...

Tilt angle is up to 60 degrees, accuracy is down to 2cm.

Working Continuously Gnss Kolida


Thanks to the low consumption operation system design, K7X can work up to 15-20 hours in RTK rover mode, up to 20 hours in static mode. Type-C USB port is onboard now.


A reinforced battery compartment has been designed for K7x, there are three times protection to prevent the battery "drop off".

The top cap, seal ring, bodywork, indicator light, painting... everything is new and quality.


Our goal is to provide an exceptional feel and durability.
