Results of the test campaigns

A cross check can still be made if the camera clock has been synchronized with the

PC-board internal clock time, reading the exif

data contained in each image where date

and time are saved. Long runs of more than 4 hours of operations showed that each image

was correctly acquired and saved.

After the first testing phase, a Computer-In-the-Loop (CIL) and an Hardware-In-the-

Loop (HIL) test campaigns were performed to evaluate system response and better

understand the interaction with the pilot. The CIL layout is shown in Figure 84, where a

joystick is used as input device to control aircraft‟s command surfaces. The aircraft‟s

dynamics is simulated using a Simulink model and according to its position and attitude,

both GPS and IMU data are provided to the FASTER model.

Exif stands for Exchangeable image file format and is a specification for the image file format used by

digital cameras. The specification uses the existing JPEG or RAW file formats with the addition of specific

metadata tags that could contain: date and time information, camera settings like aperture, shutter speed,

focal length and ISO value, and a thumbnail for previewing the picture.
