The SMC remote stations distribution (b) in Azores (c) across continental Portugal (top) and in Madeira (bottom). that a particular RFI affecting a particular frequency band simultaneously impacts the importance and effectiveness of the data measured in other frequency bands. The understanding of these particularities of an EESS or MetSat by administrations is not always clear-cut, but it is important in implementing a suitable spectrum monitoring and enforcement policy addressing EO mission requirements. Before mobilizing and deploying further resources, (a) (b) FIGURE 4. ANACOM SMC mobile stations in Porto. (a) General purpose SMC mobile station.

In this sense, the technical characteristics and operational parameters of the affected station are also studied to check compliance with IEEE GEOSCIENCE AND REMOTE SENSING MAGAZINE DECEMBER 2022
