“…In addition to the rubber balloon observations, seven high-altitude balloon observations were performed on 7 and 18 November 2003; 5, 13, and 27 December 2003; and 6 and 9 January 2004. The high-altitude balloons used were made of very thin polyethylene films (5.6 mm) with a diameter of about 24 m and a length of about 33 m (a volume of about 5000 m 3 ) (Yamagami et al 2004) and reached a height of about 40 km. Calm weather conditions with surface winds weaker than 3 m s 21 are required for a successful launch.…”

“…The distances between the cities are of the order of 25 to 50 km, and these distances are suitable to find the position of a repeater placed at an altitude of the same magnitude, that is, in the Earth's stratosphere. One example of a platform compatible with this altitude is the scientific balloon, which can surpass altitudes of 50 km and fly for more than 40 days (Yamagami et al, 2004). For this present work, a scientific balloon is considered as a simulated platform where the repeater is meant to be installed, flying at an altitude of 30 km, over four different locations, also shown in Figure 2.…”

“…The density was set to 920 kg/m 3 , 21) and in order to reduce the weight, a thin material with a thickness of 3.4 ®m was used. 22) Furthermore, the nylon film of 30 ®m thickness 23) with a density of 1100 kg/m 3 was selected for the outer skin. 24) Let us consider the volume of the gas cylinder V cylinder next.…”
