System and method for monitoring a territory

The present invention relates to an environmental monitoring system (1) comprising a central system (3) and a plurality of remote measuring units (2) operatively connected to the central system (3). Each remote measuring unit (2) comprises a receiver (200-203) intended to receive a radio signal transmitted from a satellite (4) and to measure the power of an electric signal generated by the reception of the radio signal, and a transmitting system (205) for transmitting to the central system a datum associated to the measured power, information about said satellite and information about the measuring unit. The central system (3) comprises a receiver (301) for receiving the data transmitted from the remote measuring units. A processing unit (3020) of the central system is operatively connected to the receiver (301) and it is configured for calculating, on the basis of the data transmitted from the remote measuring units (2), the trajectories of the radio signals received from the measuring units, the intensity and position on the territory of weather events that attenuate the radio signals received from said plurality of measuring units. An environmental monitoring method and a television receiver are also described to be used as component of the environmental monitoring system.
