Ardu Simple - simpleRTK2B Stand Alone Application Board

The simpleRTK2B is a stand alone application board that allows to evaluate multi-band GNSS technology including RTK functionality. It's based on u-blox ZED-F9P module and is fully compatible as a shield with Arduino, STM32 Nucleo, Rasberry Pi or as an external GNSS for Pixhawk autopilot.

About RTK GPS Solutions:

Real-time kinematic (RTK) positioning is a satellite navigation technique used to enhance the precision of position data derived from satellite-based positioning systems (global navigation satellite systems,GNSS) such as GPS, GLONASS, Galileo, and BeiDou. It uses measurements of the phase of the signal's carrier wave in addition to the information content of the signal and relies on a single reference station or interpolated virtual station to provide real-time corrections, providing up to centimeter-level accuracy.  With reference to GPS in particular, the system is commonly referred to as carrier-phase enhancement, or CPGPS.  Applications include land survey, hydrographic survey, and in unmanned aerial vehicle navigation.
