Accelerate your go to market
Instead of starting a product development that will take you 2-3 years and cost you a fortune in engineering time, prototypes and headaches… why not start selling tomorrow?

OEM format
We removed any logo from our enclosures so you can build your own product and brand.

Compatible with basically anything
Dual RS232, Ethernet, CANBUS, USB & up to 8 configurable I/O. Just explain us which protocol and connector you need, and let SBC do the rest, plug and play.

All protocols are possible with SBC: NMEA, HDT, UBX, RTCM, TSS1, PASHR or just define your own.

Programming made simple
Forget about long learning time to program your application. We took care of the complex things so you can focus on developing your application. Just Copy&Paste from a few examples to build your own code. Or just send us your requirements and we can program it for you.

Radio link flexibility
simpleRTK2B-SBC has accessories for almost any wireless technology: WiFi, 2G/3G/4G, BT, ISM, UHF…

Raw GNSS measurements
Read the raw data from the satellites without any post-processing and store it in the built-in memory or SD card slot. Or send it over Ethernet or any other interface.

simpleRTK2B-SBC supports different operating modes

Standalone simplest way of reaching <1m position accuracy without range limitations
The most basic configuration is to use simpleRTK2B as a standalone dual band GNSS receiver.


Base – rover configuration – get <2cm accuracy with a maximum range of 20km from the base station
Use two simpleRTK2B configured as base station and rover.

Base – multiple rovers configuration – get <2cm accuracy with a maximum range of 20km from the base station
Configure one simpleRTK2B as base and broadcast its RTK corrections to as many rovers as you want to get centimeter level accuracy.


RTK moving base configuration – get <2cm accuracy and a complete Attitude and Heading Reference system with a maximum range of 20km from the base station
Configure one simpleRTK2B as base and two/three simpleRTK2B as rovers, mounted on a drone, car, ship, …

Standalone with VRS/SSR corrections – get <2cm accuracy without range limitations (subject to mobile network coverage)
Use simpleRTK2B as a standalone GNSS RTK receiver combined with SSR corrections to get centimeter level accuracy.
Equip your simpleRTK2B with the 4G or satellite module and you will get centimeter level accuracy without range limitations.
