| Abstract: | During last few years several new sub-systems for balloon were developed and are being regularly used in the balloon flights. Some of these sub-systems are i) positive monitor for magnetic ballast release using an opto-electronic device ii) one-way pressure switch to terminate flight for runaway balloon iii) in-flight payload reel down system for atmospheric science experiment. The design, usage and performance of these and other sub-systems will be presented. |
