A global navigation system logger with Adafruit Feather #Feather #GNSS


Paul Clark posts on GitHub a GNSS PPK RAWX Logger. (Global Navigation Satellite Systems GPS/ etc.) PPK (post processed kinematic) data logger. PPK is usually better for robotic applications. RAWX is a data format.

This project uses an Adafruit Feather M0 Adalogger and a SparkFun GPS-RTK2 Board which incorporates the u-blox ZED-F9P dual band (L1 + L2) GNSS receiver.

The RAWX files logged by this project can be processed using rtklibexplorer’s version of RTKLIB describes how to connect the Adalogger to the SparkFun GPS-RTK2 board describes how the Arduino code communicates with the F9P using the u-blox UBX binary protocol to enable and log the RAWX messages.

The code is written in Arduino. See the GitHub repo for details.


Stop breadboarding and soldering – start making immediately! Adafruit’s Circuit Playground is jam-packed with LEDs, sensors, buttons, alligator clip pads and more. Build projects with Circuit Playground in a few minutes with the drag-and-drop MakeCode programming site, learn computer science using the CS Discoveries class on, jump into CircuitPython to learn Python and hardware together, TinyGO, or even use the Arduino IDE. Circuit Playground Express is the newest and best Circuit Playground board, with support for CircuitPython, MakeCode, and Arduino. It has a powerful processor, 10 NeoPixels, mini speaker, InfraRed receive and transmit, two buttons, a switch, 14 alligator clip pads, and lots of sensors: capacitive touch, IR proximity, temperature, light, motion and sound. A whole wide world of electronics and coding is waiting for you, and it fits in the palm of your hand.
