The sum of the percentages in the table implies that all of data collection platforms (High rate, Low Rate, Regional and International) are operating at the same time within the satellite footprint. This is a worst case assumption. 6.1.4 Application of the narrow-band criterion The narrow-band criteria for each satellite system are presented in Tables 3-1, 3-2, 3-3, 3-4 and 3-5. It is presented as a power level in dBm. It represents the maximum level for a single interfering transmitter. The specified spurious emissions level for data collection platform is significantly lower than the interference threshold. Table 6-7 shows the comparison of the sensitivity levels for four cases, one each for the LEO and GEO orbits and two for MEO orbits, compared to the direct emission levels from the data collection platforms.

The mean interference power was calculated from integration similarly to the LEO case. The results of the calculation of the percentage of the interference threshold that the anticipated number of transmitters is contributing to the MSG GEOSAR are listed in Table 6-14. 6-14 Calculation of the percentage of the interference threshold that the anticipated number of transmitters is contributing to the MSG GEOSAR MSG Sensitivity Range (MHz) Mean Interference Power (dBW) Bandwidth (Hz) Number of simultaneous transmitters Density dB (W/Hz) Threshold dB (W/Hz) Margin (dB) Percent total (%) –182.74 850 000 39.31 –226.085 –172 –54.08 401-405 –182.74 4 000 000 185.00 –226.085 –177 –49.08 0.00123 –182.74 900 000 43.94 –225.85 –182 –43.85 0.00412 0.0057460
