Using Arduino Due and Raspberry Pi with 10Hz Alpha RTK

Many customers have interest in using Arduino and Raspberry Pi for real-time robotic control RTK projects. Here we share two simple  videos showing how Arduino Due and Raspberry Pi can be hooked up with Alpha, using the example NMEA parser code to extract position, time, status information, and printout the results on screen. The RTK base data is sent to Alpha using Adafruit CP2014 USB-to-Serial breakout board. The UPM-Lite Kit is used in this demo.


Other Arduino boards have 4byte floating point number, insufficient latitude/longitude decimal digits for RTK's precision. Arduino Due has 32bit processor and supports 8byte double precision floating point.

The source codes can be download from bottom of this page, clicking the SUPPORTS Tab.

Compared to other L1 5Hz GPS/GLONASS RTK or 10Hz GPS RTK,  Alpha's 10Hz GPS/GLONASS or GPS/BDS RTK has advantage of (1) faster RTK convergence time using dual satellite constellations, (2) faster 10Hz response time for robotic control.  

We look forward to see what interesting robotic projects you plan to do with Alpha !
