A clone of the Adafruit Ultimate GPS FeatherWing but with the u-blox NEO-M8T replacing the GlobalTop FGPMMOPA6H. The NEO-M8T can receive signals from GPS, Galileo and GLONASS or BeiDou concurrently and supports both SBAS and QZSS. It also provides Multi-GNSS Raw Measurement (RAWX) Data which can be used for Post-Processed Kinematic (PPK) positioning.

See LEARN.md for more details.

POST_PROCESS.md contains results of a first time successful attempt at post-processed kinematic positioning using rtkexplorer's demo5 version of RTKLIB.

See NEO-M8T_GNSS_FeatherWing.pdf for the schematic, layout and Bill Of Materials.

The Eagle directory contains the schematic and pcb design files.

The Arduino directory contains code for the Adafruit Feather M0 Adalogger which will log RAWX data to SD card.
