Zubax GNSS is a high performance open source positioning module for outdoor environments, interfaced via doubly redundant UAVCAN bus. It includes a state of the art GPS/GLONASS receiver, a high precision barometer and a 3-axis compass.

• LEARN MORE
• DOCUMENTATION AND TUTORIALS

• Install ARM GCC toolchain version 4.8 or newer
• Init the sources:

git submodule update --init --recursive

• Build:

cd firmware
make RELEASE=1 # RELEASE is optional; omit to build the debug version

• Optionally, generate release binaries:

cd firmware
./make_binaries.sh

Avialable loaders:

./zubax_chibios/tools/blackmagic_flash.sh   # Black Magic Debug Probe
./zubax_chibios/tools/stlink_flash.sh       # ST-Link v2

First, make sure to generate release binaries as described above. Then feed the signed binary (it will be named as *.uavcan.bin) to the UAVCAN firmware update server.

Source of the UAVCAN bootloader for this board can be found at the PX4 source repository.
