A space based or aeronautical augmentation system comprises space based or aeronautical broadcasting means adapted for retransmitting streams of messages NOF m.j transmitted by broadcasting ground stations, one or more observation and reception ground stations for signals transmitted by the satellites of the GNSS global navigation system and by the N space based or aeronautical broadcasting means. The space based or aeronautical augmentation system further comprises K computation centres, located on geographically remote sites, and each configured to formulate i-th streams of messages NOF i.j, j varying from 1 to j, such that all the data streams NOF i.j, independently of the computation centre CPF#i which formulate them, comprises one and the same sequence of types MTs of messages, which is independent of the space based or aeronautical broadcasting means.
