OBC
The onboard computer (OBC) is the other brain of the system, with a real CPU and GPU, as opposed to
microcontrollers on the avionics. In case of an issue with the OBC, the avionics can take over and ensure
the basic safety of the system.
T
RANSMITTER
The transmitter offers a reliable wireless link between the GCS and ELIOS 3. It handles the video
transmission, the pilot controls, and the telemetry between the aircraft and the ground control system.
4K
OPTICAL CAMERA
The frontal camera payload houses a 4K optical camera. It can record 4K (2160p 30fps), which is
recorded onto the CAM SD card. 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 exposure time and ISO of the optical camera are fully automated. The user can compensate for the
exposure value through the EV settings to get a brighter or darker image if needed.
The 4K optical camera allows users to record video into this resolution:
-
4K UHD: 3840 x 2160 at 30 fps, data-rate 600MB/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 a maximum of 35 images can be taken in a single flight when in 4K UHD mode. The resolution of
the still images is always 12MP.
Note: the camera data, videos and photos are recorded in 128GB SD cards,
However, this SD card cannot be removed from the aircraft. The data can be downloaded to a PC via the
Flyability Inspector software.
SSD
Onboard the aircraft there is a solid-state drive card (SSD) with 500 GB of memory. This SSD is used to
record all data from the onboard computer (OBC). The flight data can be downloaded to a PC with the
Flyability Inspector software.
