RFI estimation from Non-GSO satellites based on two line element assisted equivalent power flux density calculations

As a result of out-of-band emissions and spurious emissions from air-borne or space-borne transmitters simulations and analysis methods have been developed. These methods were developed to determine the amount of interference such a transmitter could cause. The method discussed and applied in this paper is the equivalent power flux density (EPFD) method, which is formally described in international telecommunication union (ITU) recommendations. Up until this point this method has been implemented in MATLAB, which can be used for the determination of the amount of data loss in radio telescopes due to the unwanted emissions of the Iridium satellite constellation. In this paper, it is proposed to use the two line elements (TLEs) instead of the licensed Satellite ToolKit in the EPFD calculation. A theoretical case has been implemented, which is adaptable to the user preferences. The flexibility of the algorithm has been improved, while computational time remains in the same order of magnitude
