Resumen:
As small satellites become more capable throughminiaturized electronics and on-board processing, constellationsof low-cost satellites lunched in Low- Earth Orbit (LEO) becomefeasible. The increase in the number of LEO satellites drives theneed for frequency coexistence between the LEO constellationsystems with the already existing geostationary (GSO) satellitenetworks. In this context, it is crucial to design the communicationlinks paying special attention to interference analysis.This is particularly true when the LEO satellite constellationexploit inter-satellite communication links (ISL). In this paper,a radio frequency interference analysis based on simulation ofthe dynamic satellite constellation is presented and the designparameters of the inter-satellite links are analyzed. The resultssuggest that carefully choosing the design parameters of the intersatellitelinks, spectrum coexistence of LEO and GSO networksmay be possible.
