The Best-in-Class GNSS Engine

The integrated advanced 1598-channel GNSS technology helps K7/k58 plus 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/k58 plus can transmit to 10 km away by only 1 watt power consumption.

kFill Technology And Upgraded IMU

1. 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.
2. 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.

Working Continuously Up To 20 Hours

1. Thanks to the low consumption operation system design, K7/k58 plus 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.
2. A reinforced battery compartment has been designed for K7/k58 plus, there are three times protection to prevent the battery "drop off".
