RTK Modes

simpleRTK2B 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 GNSS application board.
Connect it to your Arduino, computer or smartphone and enjoy your position in seconds.


Base – rover configuration – get <1cm accuracy with a maximum range of 35km from the base station
Use two simpleRTK2B configured as base station and rover.
Connect the base station and/or rover to your Arduino, computer or smartphone and you will get both positions in seconds.

Base – multiple rovers configuration – get <1cm accuracy with a maximum range of 35km 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.
Connect it to your Arduino, computer or smartphone and you will get your position in seconds.


RTK moving base configuration – get <1cm accuracy and a complete Attitude and Heading Reference system with a maximum range of 35km from the base station
Configure one simpleRTK2B as base and two/three simpleRTK2B as rovers, mounted on a drone, car, ship, …
Connect it to your Arduino, computer or smartphone and you will get your position, attitude and heading in seconds.

Standalone with RTK/SSR corrections – get <4cm accuracy without range limitations (subject to cellular network coverage)
Use simpleRTK2B as a standalone GNSS application board combined with simpleSSR receiver to get receive corrections and get centimeter level accuracy.
Connect it to your Arduino, computer or smartphone and you will get your position in seconds.
