Featuring a powerful 440 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. (For advanced users who need to maximize the working speed and satellite signal tracking ability, a 555 channels GNSS mainboard is optional.) 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.
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. 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 .
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. Corner of wall? Points underneath pipe? Points occupied by car? These targets are no more accessible..
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. 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.

What is it used for?
This receiver can be used in all applications where a centimetre accurate position is needed:
- GIS applications
- UAV Base Station
Comparable receivers from other brands
Global GPS Systems is currently in the process of independantly testing every single receiver on the market. In collaboration with an highly recognised surveying company we will be testing all receivers on its performance in increasingly more difficult environments, accuracy claims, Time to first fix, cold start and more.
