1. A satellite communication device comprising an antenna for communicating with a satellite, the device comprising:
- a measurement module configured to carry out a plurality of measurements of the equivalent isotropically radiated power of the antenna;
a reception module suitable for receiving, periodically, an equivalent isotropically radiated power setpoint to be applied to the signal transmitted by said antenna, said setpoint being computed by control equipment to observe a target link budget on the satellite link between said communication device and another device of the same network;
a computation module configured tocompute an average, over a first time interval, of said plurality of power measurements,compute an average, over a second time interval substantially identical to said first time interval, of said received power setpoints,compute the deviation between the average of the power setpoints and the average of the power measurements; and
a transmission module suitable for transmitting said deviation to said control equipment, via said satellite.

Abstract
In the field of satellite communication systems, a method is provided for managing communication resources allocated by central control equipment to the various terminal communication devices within a global satellite communication system. In particular, the management of communication resources by way of the monitoring of the equivalent isotropically radiated power transmitted by a terminal of the satellite communication system is provided.

12. A method for controlling the resources allocated within a satellite communication system, comprising at least one satellite communication device and equipment for controlling the resources within said system, said method comprising the following steps:
-
periodically computing an equivalent isotropically radiated power setpoint as a function of a target link budget to be attained on the satellite link between a first communication device and a second communication device, carrying out a plurality of measurements of the equivalent isotropically radiated power of the antenna of said first device, computing an average, over a first time interval, of said plurality of power measurements, computing an average, over a second time interval substantially identical to said first time interval, of said power setpoints, computing the deviation between the average of the power setpoints and the average of the power measurements, allocating more or fewer communication resources to said first device or to other devices of the system as a function of said deviation. - View Dependent Claims (13, 14)
