Flying at night at an altitude of 1,500 ft (450 m), the S-100 regularly detected points of interest at ranges of over 3,000 m (3,300 yards), using the thermal imager on the installed IAI/Tamam POP200 stabilized EO/IR gimbal system.

The S-100 was controlled by Schiebel operators, flying preprogrammed paths that could be interrupted at any time to survey specific points of interest or known hot spots used by human traffickers.

The payload itself was operated by the same police officers that normally operate similar payloads aboard the BM.Is manned helicopters. The payload operator communicated with both Austrian and Slovakian police and military teams in the field to investigate any suspicious activity detected from the S-100. Video was recorded onboard and at the control station, as well as being forwarded via network to a nearby command post.

The two-week demonstration is the first known integration of a UAV system in live border patrol operations along the European Union (Schengen area) border. The successful tests bode well for future UAV employments along the border, which is set to expand in 2007.

All flights were staged from the top of Braunsberg nearby the town of Hainburg, a 346 meter (1,100 ft) tall mountain overlooking the Danube River and the Slovakian capital of Bratislava. Two standard missions were programmed, one 50 km (31 mi) to the north, along the March River, and one 20 km (12 mi) to the south along the border to the town of Kittsee. The flight paths, programmed under the supervision of AustroControl, the Austrian aviation authority, avoided flight over built-up areas, as well as the nature preserve along the March river.
