Abstract
A method for determining operational constraints for a first constellation of non-geostationary satellites transmitting towards a terrestrial station with respect to a second constellation of non-geostationary satellites linked with the station, the constraints comprising a maximum transmission power of the satellites of the first constellation, the method comprising: determining triplets of limit values (θ, ϕ, I/N) of two angles (θ, ϕ) and of an interference-to-noise ratio (I/N), the angles (θ, ϕ) defining a position of a satellite of the first constellation relative to the station and to a satellite of the second constellation and the interference-to-noise ratio being the ratio between interferences transmitted by the first constellation on a link between the station and the satellite of the second constellation and the noise (N) of the link, the determination of the triplets being performed so that a distribution of signal-to-noise and interference ratios (R) aggregated over a time interval is greater than a reference distribution; determining at least the maximum transmission power of at least one satellite of the first constellation from the triplets.
