Results of the test campaigns

105

The two emulators generates the same nmea strings for the GPS and the angle mode

packet binary data output for the I.M.U. With the HIL setup more accurate simulations of

the flight campaigns were made testing the functionalities of the updated version of the

tunnel in the sky interface.

The results of the third flight campaign simulation over the Brisighella area are

reported in the following images. Figure 86 shows the planned trajectory with the

FASTER planning tool (more detail in Chapter 5). Then the waypoint list file has been

created and copied inside the memory card by the Advantech PC/104+ board inside the

FASTER rack box.

Figure 86: Simulation of the third flight campaign (Brisighella area) using the HIL setup

The entire flight (about 50 min) was simulated using the HIL setup and then the

results were analyzed with an appropriate tool developed in Matlab. This tool takes into

account both the planned and flown trajectories; for each planned waypoints the script

searches for the two nearest waypoints into the flight log. This search is time driven,

based on total elapsed flight time; only waypoints at the same mission time percentage

(±10%) are searched in order to avoid errors during stripes crossing.
