Assessment of satellite power flux-density limits in the 2025-2300 MHz frequency range, part 1

An assessment of the line-of-sight (LOS) power flux-density (pfd) limits for satellites operating in the 2025-2300 MHz frequency range was conducted. Two computer models were used in the analysis. Modifications to these models were suggested in order to enhance their accuracy in the evaluation of the pfd limits in this and other shared bands. Distinctions were made between the satellites in geostationary satellite orbit and those in nongeostationary orbits. Two different sets of limits were calculated, one for the satellites in the geostationary satellite orbit and the other for the satellites in nongeostationary satellite orbits. These limits were calculated using the technical characteristics of equipment in the 2025-2300 MHz frequency range. The preliminary calculations using the existing computer models indicate that the pfd limits for the satellites operating in this frequency range may be relaxed.
