- Telecommunication system for the transmission of digital information between at least one content provider (F 1), at least one set of users U i, comprising at least the following elements: • a network (R 1) of geostationary satellites comprising at least one geostationary satellite (G 1), at least one access station (SAG 1) connected to one or more content providers (F 1), and at least one geostationary satellite subscriber station (SG 1 or SG 2), • a network (R 2) of non-geostationary vehicles comprising at least one network access station (SAN 1), at least one non-geostationary vehicle network user station (SN 1), at least one vehicle (NG 1) in low earth orbit comprising means adapted to the exchange of low-latency data between a network access station (SAN 1) and the non-geostationary vehicle network (SN 1), • a local loop (B 1) comprising a plurality of users U i, • a nanocache (N 1) connected to the subscriber station (SG 2) of the GEO network R 1 and adapted to store content from the content providers (F i, with i at least equal to 1) as a function of the profile of the users, the nanocache (N 1) being also connected to the local loop (B 1) and to the subscriber station (SN 1) of the NGSO network (R 2), • a microcache (M 1) for the storage of content from the content provider or providers (F 1) received via one of the subscriber station (SG 1) of the geostationary satellite (G 1), the microcache (M 1) being also connected to the NGSO network (R 2) via access stations (SAN 1), the microcache (M 1) having greater storage capacity than the nanocache (N 1), (M 1) storing a priori all the content from the geostationary satellite (G 1), • at least one CDN (CON 1) comprising a routing algorithm adapted to determine a microcache to be used to find the content requested by a user that is not stored in a nanocache near the user. • a network (R 1) of geostationary satellites comprising at least one geostationary satellite (G 1), at least one access station (SAG 1) connected to one or more content providers (F 1), and at least one geostationary satellite subscriber station (SG 1 or SG 2), • a network (R 2) of non-geostationary vehicles comprising at least one network access station (SAN 1), at least one non-geostationary vehicle network user station (SN 1), at least one vehicle (NG 1) in low earth orbit comprising means adapted to the exchange of low-latency data between a network access station (SAN 1) and the non-geostationary vehicle network (SN 1), • a local loop (B 1) comprising a plurality of users U i, • a nanocache (N 1) connected to the subscriber station (SG 2) of the GEO network R 1 and adapted to store content from the content providers (F i, with i at least equal to 1) as a function of the profile of the users, the nanocache (N 1) being also connected to the local loop (B 1) and to the subscriber station (SN 1) of the NGSO network (R 2), • a microcache (M 1) for the storage of content from the content provider or providers (F 1) received via one of the subscriber station (SG 1) of the geostationary satellite (G 1), the microcache (M 1) being also connected to the NGSO network (R 2) via access stations (SAN 1), the microcache (M 1) having greater storage capacity than the nanocache (N 1), (M 1) storing a priori all the content from the geostationary satellite (G 1), • at least one CDN (CON 1) comprising a routing algorithm adapted to determine a microcache to be used to find the content requested by a user that is not stored in a nanocache near the user.
