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.

Centimeter level precision
<1cm precision with base-rover
<1cm precision with NTRIP corrections
<4cm precision with SSR corrections
<1.5m in standalone mode
<0.9m in standalone mode with SBAS coverage

Ready for SSR correction services
Get worldwide coverage over the air corrections to achieve amazing centimeter level accurcay without the need of a base station.

Advanced configurations
• 2x GPS: for heading functionality
• 3x GPS: for full attitude calculation
• Dead reckoning: sensor fusion for seamless navigation during short GPS signal interruptions

Typical convergence times of modules based on:
– Single band RTK (NEO-M8): <60s
Multi band RTK (ZED-F9P): <10s

• Reduces convergence time
• Increases ambiguity fixing rates
• Increases overall cm-level position availability

• GPS & GLONASS: readily available in L2C/L2OC
• Galileo: full E5b constellation by ~2020
• BeiDou: B2I available until migration to B2a

Radio link flexibility
simpleRTK2B can be used with almost any radio link: WiFi, 2G/3G/4G, BT, ISM, UHF…

Raw GNSS measurements
Read the raw data from the satellites without any post-processing

RoHS compliant

simpleRTK2B SBC


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.
