      The purpose of this study is to solve the problem of the determination of the exact capacity and performances of a satellite location and data collection system using random access. Here is described the method we apply in the particular case of the ARGOS system; the TIROS-N and NOAA-A to G satellites will be equiped with the ARGOS on-board experiment and will ensure an operational service from 1978 to 1985 at least. The results we obtained are significantly better than the first estimations and should allow us to increase the number of the platforms.
