Abstract (en)
[origin: FR2735306A1] The system includes a number of balloons which are positioned at heights between 19.2 and 56 km above ground. Each balloon forms a telecommunications node and allows transmission and reception of digital signals using CDMA. Reception is via a number of antennae which can receive relatively weak transmissions. The received signals at the node are decoded, and the source identified. The system is arranged to provide maximal spectrum use, providing signal transmissions without interference.
