2cm/ 60° Tilt Survey
All Constellation Signal
Hot-swappable & Extra Power
More Advanced GNSS Engine
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.)
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
More Durable and Rugged
Kolida 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 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.
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
Measure where others can't
Corner of wall? Points underneath pipe?
Points occupied by car? These targets are no
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
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)
SDL400 built-in radio features
anti-interference capability, so K1 can
work close to power plant, transformer
substation, mobile signal tower and other
Kolida K20s and K20s IMU employs Linux system, it helps
surveyors to accomplish their missions
easier, faster and more accurate by delivering
exceptional quality and innovative features.
