A method is provided for controlling a set of at least two satellites adapted to provide a service used by at least one portion of the set of the said satellites at a given moment, in which, continuously or pseudo-continuously, a mean value of the longitudes of the respective ascending nodes of each satellite is computed, and, for each satellite, a correction of trajectory of the satellite is applied by regulating the longitude of the ascending node on a setpoint equal to said current mean value.

1. A method for controlling a set of at least two satellites configured to provide a service used by at least one portion of the set of said satellites at a given moment, the method comprising: computing, continuously or pseudo-continuously, a mean value of longitudes of respective ascending nodes of each satellite; andcontrolling, for each satellite, a correction of trajectory of the satellite by regulating a longitude of an ascending node on a setpoint equal to said mean value. 2. The method according to claim 1, wherein the longitude of the ascending node of each satellite is measured, respectively, when the satellite is visible from a ground control station. 3. The method according to claim 2, wherein the ground control station is connected to other ground control stations via a communication network. 4. The method according to claim 1, wherein a single ground control station is used for the set of the said satellites. 5. The method according to claim 1, wherein controlling the correction of the trajectory of the satellite is deferred to a moment when the satellite no longer participates in provision of said service. 6. The method according to claim 1, wherein the computing and controlling are carried out autonomously by the set of satellites, the controlling being configured to communicate to broadcast values of the ascending node longitudes necessary for the computing of said mean value. 7. A system for controlling a set of at least two satellites configured to provide a service used by at least one portion of the set of said satellites at a given moment, the system being configured to: compute, continuously or pseudo-continuously, a mean value of longitudes of respective ascending nodes of each satellite; andcontrol, for each satellite, a trajectory correction of the satellite by regulation of a longitude of an ascending node on a setpoint equal to said mean value.
