A method of multicasting collective information via a non-geosynchronous satellite telecommunication system which provides interactive individual connections and covers a multicast cell in which each user has a communication terminal including two data sender/receiver systems each of which is able to exchange data with a satellite independently of the other system and which are used alternately in time with the passage of said satellites so that between two changes of satellite one system is active and the other is held in reserve, in which method said collective information is broadcast to all the satellites on at least one dedicated carrier which is received by said system of each terminal that is held in reserve.
