ARK-OS

ARK-OS is ARK's companion computer software suite: a set of systemd services for MAVLink routing, video streaming, flight log management, firmware updates, and network RTK corrections, plus a web UI to manage it all. It comes pre-installed on the ARK Jetson image.

ARK-UI

The web UI is served at http://jetson.local (or the Jetson's IP). Pages: System (hardware and resource info, hostname), Autopilot (status, firmware update, reset), Connections (WiFi/Ethernet/LTE, data usage), Services (start/stop, autostart, logs, config editing), Video (live camera stream), and Logs (flight log download and upload to Flight Review).

Services page — start/stop services, toggle autostart, view logs, edit configs

Services

See the Services page for what each service does and which are enabled by default.

Command-Line Tools

ARK-OS puts its operator scripts on PATH (open a login shell and run them by name):

mavlink_shell.py              # interactive PX4 NSH shell over MAVLink
px4_shell_command.py <cmd>    # run a single PX4 console command
flash_firmware.sh <fw.px4>    # flash flight controller firmware
reset_fmu_fast.py             # reset the flight controller
reset_fmu_wait_bl.py          # reset the flight controller into bootloader
jetson_serial_number.py       # print the carrier serial number
can_check.py can0             # check DroneCAN traffic on a CAN interface
check_cameras.sh              # stream-test the CSI cameras
check_fan.sh                  # verify the cooling fan

Updating ARK-OS

ARK-OS is distributed as a Debian package on the releases page. To update a device, run the install script from a clone of the repo on the Jetson:

git clone https://github.com/ARK-Electronics/ARK-OS.git
cd ARK-OS
sudo ./packaging/install_ark_os.sh --ark-os-version=X.Y.Z

Upgrading resets the service configuration under /etc/ark-os/ to packaged defaults — reconfigure via the web UI afterward.
