More Advanced 

GNSS Engine

Featuring a powerful 692 channels GNSS mainboard inside, K20s 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.

10 Innovations to Increase Efficiency

More than 10 programs or functions were re-designed to make your work flow simpler and smoother, let you to work easier and comfortable, help you to get more reliable working result.

More Durable and Rugged 

K20s is fully sealed, has a IP 68 level proof. The built-in battery has 10,000 mAh capacity and can work 8 to 14 hours as RTK rover, with only one recharge.

Work Safer and Easier

Thanks to the inertial measurement technology, K20s 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.

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.
