Popis:	Artificial satellites perform downlink communication or transmission with earth stations. These transmissions are made from an array of antennas chosen to increase directivity and gain in the transmission of the electromagnetic signal. It occurs that the signal from the array of antennas can infer a disturbance by electromagnetic acceleration, which results in disturbances in the orbital components of the satellite. Taking the StarOne C1 satellite, with EIRP = 44 W, mass = 1918 kg and with a planar antenna array, we developed an acceleration model for this type of antennas. A satellite orbiter propagator was developed by the Runge-Kuta method, and from the technical characteristics of this satellite and the state vector values (position and velocity), we were able to calculate an electromagnetic acceleration of the order of 10^{-9} m/s^{2}.
