AVIONICS
The avionics are the brain of the ELIOS 2. On top of its flight control role, the Avionics coordinate all
ELIOS 2 sub-systems.
TRANSMITTER
The transmitter offers a reliable wireless link between the GCS and ELIOS 2. It handles the video
transmission, the pilot controls, and the telemetry between the aircraft and the ground control system.
4K OPTICAL CAMERA
ELIOS 2 embeds a 4K optical camera. Its 4K (2160p 30fps), FHD (1080p 30fps) footage and 12.3MP still
images are recorded onto the CAM SD card. The camera transmits a FHD (1080p) live video feed to the
GCS.
The camera is mounted on a servo motor, allowing it to tilt up or down.
DO NOT TILT THE CAMERA BY HAND, AS THIS MAY DAMAGE THE
SERVO MOTOR.
The full 4K optical camera is fully automated. The user can compensate the Exposure Value through
the EV settings to get a brighter or darker image at will.
The 4K optical camera allows to record video in two different resolutions:
-
4K UHD: 3840 x 2160 at 30 fps, data-rate 600MB/min
-
FHD 1080p: 1920 x 1080 at 30 fps, data-rate: 100MB/min
The video recording automatically starts when the drone is armed and stops when the drone is
disarmed. Provided that there is enough available space on the CAM SD card.
The 4K optical camera allows the user to take 12MP 4000x3000 still images with the POI button. It is
important to note that max 35 images can be taken during singlea flight when in 4K UHD mode.
There is no limitation when in FHD mode
The resolution of the still images is always 12MP, regardless of the video recording mode.
THERMAL CAMERA
The FLIR LEPTON thermal camera is coaxially mounted next to the video camera and can also be tilted
up and down. The thermal camera recording automatically starts when the drone is armed and stops
when the drone is disarmed. The footage is saved in the LOG SD card and can be reviewed using
Flyability Inspector. The pilot can also display the live video feed from the thermal camera during flight.
CAM SD CARD
The CAM SD card records the video footage and still images from the 4K optical camera while Elios is
flying.
Please only use the provided SD card, as this has been tested to ensure it meets writing speed
requirements and will ensure the proper recording of the inspection footage.
Required file system: exFAT
Recommended capacity: 64GB or 128GB
LOG SD CARD
The LOG SD card records the thermal video footage as well as the aircraft’s telemetry data. The
telemetry information contains parameters such as camera pitch angle and drone altitude, and can be
reviewed using the Flyability Inspector software.
Please only use the provided SD card, as this has been tested to ensure it meets writing speed
requirements. Note that the drone is not able to fly without a LOG SD card.
Required file system: FAT32
Recommended capacity: max 32GB
AV SD CARD
The AV SD card all the aircraft’s telemetry data and internal states. This SD card acts as a black-box and
can be used by Flyability support and R&D team to diagnose any issue or incident with the ELIOS 2
system. It is also through the AV SD card that the ELIOS 2 system upgrades its firmware.
Please only use the provided SD card, as this has been tested to ensure it meets writing speed
requirements.
Required file system: FAT32
