New K5 Plus+/K9 mini+

Linux platform


3rd Tilt sensor

4G network module



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)


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, suitable to have multiple rovers work simultaneously.



SDL400 built-in radio features anti-interference capability, so K5plus+

can work close to power plant, transformer substation, mobile signal 

tower and other interference source.



The Best in Town

To improve the performance in city survey, R&D team upgraded the network module from 3G to 4G.

Under 4G mobile network, data transmission is faster and more stable.

SUPER RTK is still compatible with 3G and 2G.


Increased Working hours

Two units of 3400 mAh battery hot-swappable

& 6800 mAh Battery Rod included in Base Receiver set

External Battery Case (optional)

Practical Functions

See what others can't. K5plus+ employs Linux system, it helps surveyors to accomplish their missions easier, faster and more accurate by delivering exceptional quality and innovative features.

Full-featured radio

Send and receive integrated integrated full-featured internal radio, typical operating distance of 5 kilometers, to meet the needs of conventional operations, support for radio relay and network routing capabilities, effectively extending the working distance. Network and radio relay mode: The mobile station broadcasts the received network or station differential signal again through the internal radio station and distributes it to other mobile stations.


NFC flash touch pairing technology

The new NFC flash touch pairing technology enables quick pairing with the hands-on book to get rid of the complicated Bluetooth search and connection process in the past. With a single touch, you can successfully pair. The quick connection between the console and the host solves this problem.


Dual-mode long-distance Bluetooth

The industry’s first Bluetooth connectivity technology, equipped with 4.0 standard dual-mode long-distance Bluetooth, can connect mainstream mobile phones, tablets and other digital products, and is compatible with the 2.1 standard, connecting hands. Efficient and stable data transmission technology, Bluetooth distance farther, giving users more comfortable homework experience.


Full constell

The full constellation multi-band reception technology fully supports all current and planned GNSS satellite signals, and particularly supports Beidou B1, B2 and B3.


High speed network

4G full Netcom module, downward compatible, suitable for various signal areas, more options are available. The new network architecture supports the current mainstream CORS system.


cloud service

24-hour cloud service support, always solve the user online upgrade, online registration, remote diagnosis and other needs, so that measurement exceeds time and space.


Intelligent Core Platform

The new and efficient intelligent kernel platform has faster computing power and lower power consumption, improving the overall stability of the host. Based on the platform, it can monitor the running status of each part of the host computer in real time, and provides humanized functions such as intelligent power-saving mode, intelligent voice, and intelligent diagnosis.
