Methodology for computing the geographical distribution of maximum downlink equivalent power flux-density levels generated by non-geostationary fixed-satellite service systems using circular orbits
This Annex gives a method for calculating the geographic distribution of maximum epfd levels for non-GSO systems with circular orbits that use an exclusion angle for GSO interference mitigation. For these non-GSO systems the maximum epfd interference levels (for GSO ground stations with 3 m or greater antennas) occur on or near where the non-GSO spacecraft is inline between the GSO ground station and the GSO spacecraft. For non-GSO systems where this is not the case this approach does not apply.
