An apparatus (200) for providing an access on a vehicle (10) to a first and to a second geostationary satellites, which are available through respective satellite signals that can be used by means of respective first and second peripheral devices (33a,33b), said apparatus (200) comprising: a first and a second directional orientable antennas (20a,20b) that are configured to receive said transmitted signals returning respective received signals (21a,21b); a first and a second distribution and/or collection systems (24a,24b) of said received signals (21a,21b), said first and said second distribution and/or collection systems (24a,24b) configured to transform a first and a second received signals (23a,23b) selected between said received signals (21a,21b) into respective distributed signals (32a,32b) intelligible respectively from said first and by said second peripheral device (33a,33b); a first and a second control unit (29a,29b) configured to receive respective first and second reference signals (27a,27b) selected between said first and said second received signal (23a,23b), respectively, and said first and second distributed signal (32a,32b), and arranged to form respective first and second control signals (28a,28b) associated with said first and with said second reference signals (27a,27b); a logical decision means (26) that are configured to receive said first and said second control signals (28a,28b) from said first and from said second control units (29a,29b), and are adapted to generate a switch signal (25) if at least one of said first and of said second quality parameter (28a,28b) does not match a predetermined admissibility condition; a switch unit (22) that is configured to receive said switch signal (25) and to operatively connect each of said first and of said second distribution and/or collection systems (24a,24b) with said first or with said second antennas (20a,20b) according to said switch signal (25). |
