More Advanced GNSS Engine 

Featuring a powerful 555 channels GNSS mainboard inside, K5 IMU can track and process all the existed satellite constellations. With the utility of BEIDOU (COMPASS) signal, the data acquisition speed and GNSS signal stability are greatly improved from old generation technology.

Work safer and easier

Thanks to the inertial measurement technology, K5 IMU allows user to do a tilt survey with a maximum tilt angle of 60 °. Centering is not a must, so surveyors can stay in safe position when they measure on motorway, and don't need to step into water .

Measure where others can't

Corner of wall? Points underneath pipe? Points occupied by car? These targets are no more accessible..

Fast and accurate 

Not like tilt sensor, Inertial Measurement Unit is no more affected by the earth's magnetic field and requires no correction. It can be activated and start working within only few seconds, this fast positioning will increase measurement speed by over 30%.  

The combination algorithm of IMU + GNSS can get fixed solution faster and keep measurement results more stable, accuracy is down to 2cm.

Long Range Radio Link 

SDL400 built-in radio can send signal as far as 7 km in urban area, 8 km in suburban. The maximum coverage is up to 200 sq.km, suitable to have multiple rovers work simultaneously.

Barrier Free Measurement 

In difficult environment you may lost connection with base station or VRS network. Don't be disappointed, you can choose from 3 creative work modes to continue surveying without interruption. (Repeater/ Router/ Mobile Refenrence Station)


Kolida Gnss K1, K1Pro, K20, K20s, IMU



SDL400 built-in radio features anti-interference capability, so K1 can work close to power plant, transformer substation, mobile signal tower and other interference source.
