Audited Supplier China hot sales high performance kolida K1 pro gnss rtk
Improved Reliability Under Challenging Environment
with 672 GNSS channels solution, the usability of Glonass & Galileo satellites is greatly improved, so in harsh environment K1 PRO is able to track more satellite than other receivers and provide more reliable positioning result. (336 channels optional)
Star-Fill, Save the signal-loss
This new function will let you continue working a few minutes when radio or mobile signal is becoming very poor or even lose in blind area, the accuracy is down to 2cm.
Work Faster, Wait Less
The Maxwell 7 GNSS engine inside K1 PRO provides an ultra-fast positioning speed, typically it starts tracking satellite signal within 5 seconds after turning on, coordinate can be acquired within 10 seconds.
Star-Link Correction Infinite Freedom
2cm Accuracy Star-Link correction to it, service is available now! After subscribing to it, surveyors cansurveyors can work almost anywhere in the world without a base station or VRS network..
Fast and Flexible Inertial Measurement,
The newly developed inertial tilt survey is no more affected by the earth's magnetic field and requires no correction. The maximum tilt angle has been improved to 60 °, measurement speed is increased by over 30%.
