Scientific ballooning is being increased in the world because of the possibility of the use of up-to-date detectors and applied electronics. After the burst of the SN1987A, several institutions from several countries have shown interest in using the balloon for stratospheric balloon launching in the Southern Hemisphere. Several places in the countryside have good airports in low population density areas, ideal for balloon launching. Depending on stratospheric wind speed, flights over 25 hours are possible. Flights during turn-around and boomerang may increase flight duration. At the balloon base, only west direction flights are possible, with up to 15 hours at ceiling. With the increasing users, demands for lighter instruments and safer flights are providing new ideas for power and weight reductions. The telemetry is being improved with transmission in L band and new command system. The tracking antennas at the balloon base and at the down range station will provide location of the balloon, backing up the OMEGA system. The OMEGA system in the Southern Hemisphere is reliable and suitable for balloon trajectory. A new onboard filter is providing OMEGA data with the three stations locked at the receiver, during the worse time of day (sunrise and sunset)
